What is in the Do What You Are book summary?
Below is a preview of Sumizeit’s expert-written summary of Do What You Are by Paul D. Tieger. The full summary covers the book’s key ideas in text, audio, and video.
Do What You Are discusses the different personality types and their temperament groups, along with their respective preferences, blind spots, strengths, and weaknesses. Using the Myers-Briggs Type Indicator can help identify which of the 16 personality types are your dominant traits. Knowing your personality type will facilitate choosing the career path that will give the best chance for success because work can be easy and enjoyable when it fits with your personality, innate temperaments, and primary functions.
Personality Type Identification
The notion of personality types goes back as far as ancient Greece and was refined in 1929 by Carl Jung. Katherine Briggs and her daughter Isabel Briggs Myers developed the concept further. After many years of research and testing, they created what is now called the Myers-Briggs Type Indicator (MBTI). It relies on four preference scales and identifies 16 distinct personality types.
The value of this self-test is how it helps you identify the way you interact with the world and assists you to pick a career that brings satisfaction. If you are in the wrong career, it can feel like writing using the non-dominant hand. With enough practice, you can accomplish the task, but it may be lower quality, more difficult, tedious, and less fulfilling.
On the other hand, work that suits your personality type can actually be something you look forward to doing, and which gives you energy.
When piecing together the various personality types that are revealed by taking the MBTI, don’t believe the notion that one personality type is more prone to success than another. It can be common for our culture to value an extroverted personality above the introvert, but that is nonsense. When you are doing the work that best suits you, your success will be much easier than going against your natural grain.
Four Basic Temperaments of the Personality Types
While there are 16 distinct personality types in the MBTI, they can be divided into four temperaments.
These four temperaments can work well together, as each group’s skills are needed to complete the whole. This is especially true in large corporations where strengths in all the various areas come together to produce success.
Dominant Functions Defined
Knowing your temperament is just the beginning. Every personality type has a dominant function and when you know what your dominant function is, your work can be easy and pleasurable.
Changes in Interest Should be Anticipated
Expectations we place on ourselves at the outset of our careers can push us in the wrong direction. Traditional education forces people to make career plans while still in their teens. This is problematic because as we mature, our interests often transform and redirect. To stay satisfied in our employment, we should strive to choose careers that can change with us.
The first six years of life is where the primary personality traits develop. Then between six and twelve, the Dominant Function comes into focus.

In a world where work consumes a significant portion of our lives, choosing a career that drains rather than energizes you can lead to decades of dissatisfaction. Do What You Are by Paul D. Tieger offers a science-backed framework using the Myers-Briggs Type Indicator to match your personality to careers where you'll naturally excel.

- Career evolution across the lifespan
- Aligning natural abilities with job selection
- The myth that some personalities are 'better' for success
What are the key lessons from the Do What You Are book summary?
Personality Type Determines Work Satisfaction
Work that aligns with your personality type feels effortless and energizing, while mismatched careers feel like writing with your non-dominant hand. The difference isn't ability—it's natural fit.
The Four Temperaments Have Distinct Workplace Needs
Traditionalists thrive with structure and procedures, Experiencers need variety and action, Idealists seek meaningful and harmonious environments, and Conceptualizers want intellectual challenge and independence. Understanding these temperaments helps you recognize what environments will energize you.
Dominant Functions Shape How You Work Best
Whether you're a Dominant Sensor (facts-driven), Dominant Intuitive (big-picture thinker), Dominant Feeler (values-driven), or Dominant Thinker (logic-focused), knowing your dominant function guides you toward roles that leverage your natural strengths.
No Personality Type Has a Monopoly on Success
Society often valorizes extroversion and certain traits, but success comes from doing work suited to your actual personality. Introversion, unconventional thinking, and emotional depth are equally valid paths to fulfillment and achievement.
Your Interests and Personality Evolve Over Time
Early career decisions made in your teens may not reflect who you become in your twenties, thirties, or forties. Recognizing that personality development continues throughout life helps you anticipate and embrace career changes.
The Mid-Life Career Shift Is Often a Natural Evolution
What feels like a crisis at forty may actually be a new dominant function emerging and asking for expression. This perspective reframes career changes later in life as growth rather than desperation.
Explore Before You Commit
Creating a ranked list of potential careers based on your personality type and then interviewing people in those fields prevents you from pursuing a dream job that sounds better in theory than in practice.
Match Skills to Job Requirements
Documenting your natural abilities and past uses of relevant skills helps you articulate to employers why you're a strong candidate and reveals which roles you can naturally excel in.
Know Your Weaknesses and Address Them
Understanding the blind spots and vulnerabilities of your personality type shows self-awareness and allows you to develop strategies to manage or mitigate those areas in your chosen field.
Career Changes Are Never Too Late
An 'encore career' pursued in your forties, fifties, or beyond can be among the most fulfilling years of your professional life because you finally align your work with who you actually are.
Complement Diverse Personality Types in Teams
Organizations function best when they bring together people of all four temperaments, as each group's strengths fill in the gaps left by the others' weaknesses. Personality diversity is an asset, not a liability.
The 'Dream Job' Requires Active Search
No one will email you your ideal job; you must actively identify what it is, research it, and pursue it. This intentional approach significantly increases the likelihood of finding fulfilling work.
Consider Flexibility When Choosing Careers
Selecting careers with room for growth, variation, or transition allows you to adapt as your personality functions develop and your interests shift throughout your working life.
Money Shouldn't Be the Only Decision Criterion
Asking yourself what job you'd do for free if money weren't an issue forces you to focus on genuine fulfillment rather than defaulting to high-paying roles that don't suit your personality.
Personality Traits Develop in Predictable Stages
Primary personality traits form in the first six years, dominant functions emerge between six and twelve, and additional functions continue revealing themselves into your forties and fifties. Awareness of this progression helps you understand your evolving career needs.
Work Can Give You Energy or Drain It
Jobs that fit your personality type energize you and make you eager to begin each day, while misaligned work depletes you regardless of how well you perform. This energy differential is a key signal of career fit.
Use MBTI as a Starting Point, Not a Ceiling
The Myers-Briggs Type Indicator helps you narrow career options and understand your strengths, but personal exploration, skill-building, and real-world experience ultimately shape your career success.
Longer Working Lives Increase Importance of Fit
As people work into their seventies and eighties, spending forty or more years in the wrong career becomes increasingly costly to wellbeing. Personality-based career selection becomes more critical with extended work spans.
Your Ideal Occupation Combines Interest and Aptitude
The best careers are those where you're naturally talented AND genuinely interested. Using personality type to identify both dimensions ensures sustainable fulfillment.
Self-Awareness Is the First Step to Career Satisfaction
Understanding how you interact with the world, what energizes you, and what drains you provides the foundation for making career decisions that lead to long-term satisfaction and success.

- Making permanent career decisions in your teens or twenties based on who you are then, without recognizing that your personality continues to develop and your interests will shift
- Choosing a career primarily because it's high-paying or prestigious, even though it doesn't match your personality type—resulting in decades of uninspiring work
- Assuming that one personality type (often extroversion or logic) is superior for success, leading you to suppress your natural traits rather than leveraging them
- Failing to explore actual jobs before committing to a career path, discovering too late that the role doesn't match what you imagined it would be
- Ignoring signs of career misalignment (low energy, dissatisfaction, dreading work) and staying in the wrong role for years or decades instead of recognizing it as a signal to change

What is the expert analysis of Do What You Are?
Overview
Do What You Are by Paul D. Tieger stands as a significant contribution to the intersection of personality psychology and career development. Tieger, a recognized expert in personality typology and founder of The New England Type Institute, leverages the well-established Myers-Briggs Type Indicator (MBTI) framework to offer readers a structured approach to aligning career choices with innate personality traits. The book’s enduring relevance is anchored in its practical application of psychological theory to real-world vocational satisfaction, making it a valuable resource for career counselors, organizational leaders, and individuals seeking purposeful work.
Core Thesis
The central argument of Do What You Are is that understanding one’s personality type through the MBTI can dramatically improve career satisfaction and success. Tieger posits that work aligned with an individual’s dominant personality functions and temperament not only enhances performance but also transforms labor into an energizing and fulfilling experience. The book emphasizes that no personality type is inherently superior; rather, success stems from congruence between one’s natural predispositions and occupational demands. Furthermore, Tieger highlights the dynamic nature of personality development and career interests, advocating for adaptability and openness to change throughout one’s professional life.
Strengths
- Integration of Personality Theory and Career Guidance: The book excels at translating complex psychological concepts into actionable career advice, making the MBTI accessible and relevant beyond academic settings.
- Nuanced Temperament Framework: By categorizing the 16 MBTI types into four temperaments, Tieger provides a layered understanding of personality that aids readers in grasping broad patterns as well as individual differences.
- Practical Tools for Self-Assessment: The emphasis on identifying dominant functions and matching them with career paths offers readers concrete steps to self-discovery and vocational planning.
- Recognition of Career Fluidity: The book’s acknowledgment of evolving interests and the concept of “encore careers” reflects a sophisticated understanding of lifelong personal and professional development.
- Balanced View on Personality and Success: Tieger’s rejection of cultural biases favoring extroversion and his insistence that all personality types have potential for success is both refreshing and inclusive.
Critiques & Counterarguments
- Reliance on MBTI’s Validity: While MBTI is widely used, it faces substantial criticism in psychological research for its lack of predictive validity and reliability. Alternative models like the Five Factor Model (Big Five) offer more empirically robust frameworks for personality assessment.
- Oversimplification of Career Success Factors: The book’s focus on personality alignment may underplay the importance of external variables such as socioeconomic status, educational opportunities, networking, and labor market dynamics that also critically influence career outcomes.
- Static Personality Assumptions: Despite acknowledging personality development, the framework may still implicitly suggest relatively fixed categories, potentially limiting appreciation for the fluidity and contextual variability of personality traits over time.
- Limited Attention to Cultural and Contextual Diversity: The MBTI and its application in the book are largely Western-centric, which may reduce its applicability or require adaptation in non-Western cultural contexts where career values and personality expressions differ.
- Potential for Self-Limiting Labels: Encouraging individuals to fit into predefined personality types risks pigeonholing and may discourage exploration outside perceived natural strengths, which is contrary to some contemporary views on career development emphasizing growth and adaptability.
Who Should Read This
Do What You Are is ideally suited for career counselors, human resource professionals, and organizational leaders seeking to enhance employee engagement through personality-informed placement. Additionally, individuals at career crossroads—whether entering the workforce, contemplating a mid-life career change, or pursuing an encore career—will find practical guidance in understanding their intrinsic preferences. Readers with an interest in personality psychology and its pragmatic applications will appreciate Tieger’s accessible synthesis of theory and practice. However, those seeking a more empirically rigorous or culturally nuanced analysis of personality and career may need to supplement this book with additional sources.
Frequently asked questions about the Do What You Are book summary
What is Do What You Are about?
Do What You Are by Paul D. Tieger is a career guidance book that uses the Myers-Briggs Type Indicator to help readers identify their personality type and match it to careers where they'll naturally excel. The book explains how understanding your personality—including your temperament and dominant functions—enables you to find work that's both fulfilling and well-suited to your strengths, rather than forcing yourself into misaligned careers.
Who should read Do What You Are?
Do What You Are is ideal for anyone at a career crossroads—students choosing majors, early-career professionals considering their path, people contemplating mid-life career changes, and those simply feeling unfulfilled in current roles. It's also valuable for parents, educators, and HR professionals who want to help others find meaningful work aligned with their natural abilities and personality.
What are the main takeaways from Do What You Are?
The main takeaways are that aligning your career with your personality type leads to both success and fulfillment; understanding your temperament and dominant functions reveals what work environments and roles will energize you; no personality type is inherently superior for success—fit matters more than type; and it's never too late to change careers if your current work doesn't suit who you are. The book emphasizes that work can be easy and enjoyable when it matches your natural strengths.
How does the Myers-Briggs Type Indicator help with career selection?
The MBTI identifies your four-letter personality type from 16 possible combinations, each associated with specific temperaments and dominant functions. Tieger uses this framework to show which career fields align best with each type, allowing you to narrow your options to roles where you'll have natural aptitude and sustained motivation. By understanding your type, you can make career decisions based on fit rather than external pressure or assumptions.
Can you change careers later in life using the insights from Do What You Are?
Yes, the book strongly supports career changes at any age, introducing the concept of 'encore careers' that can be pursued with enthusiasm and fulfillment even in your forties, fifties, or beyond. Tieger argues that as your personality functions continue developing throughout your life, discovering and pursuing work that aligns with your evolved self often feels like finally doing what you were meant to do, regardless of age.
What are the four temperaments Tieger describes?
The four temperaments are Traditionalists (who value stability, order, and clear procedures), Experiencers (who thrive on adventure, variety, and hands-on action), Idealists (who seek meaningful, authentic work in harmonious environments), and Conceptualizers (who want intellectually challenging work with independence and the opportunity to innovate). Each temperament has distinct strengths and workplace needs, and organizations benefit from having all four represented.
What does it mean if my career feels exhausting even though I'm good at it?
According to Do What You Are, exhaustion in a career you're skilled at often signals a personality mismatch. Work that doesn't align with your personality type feels like writing with your non-dominant hand—possible but effortful, low-quality, and draining. If your career drains rather than energizes you despite your competence, it may be time to explore roles that better fit your personality type, where your work will feel naturally easier and more fulfilling.
