Preview of the Do What You Are Book Summary

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.

Key lessons from the Do What You Are Book Summary

Personality Type Matters More Than You Think
Your natural personality preferences directly influence career satisfaction and performance. When work aligns with your type, success comes easily; when it doesn't, even competent performance feels tedious and unfulfilling.
The Four Temperaments Framework
All 16 personality types fall into four temperaments—Traditionalists, Experiencers, Idealists, and Conceptualizers—each with distinct strengths, weaknesses, and ideal work environments. Understanding your temperament narrows down suitable career paths.
Dominant Functions Drive Performance
Sensors, Intuitives, Feelers, and Thinkers each have unique ways of processing information and making decisions. Knowing your dominant function helps you choose roles where your natural thinking style is an asset.
One Type Isn't Superior to Another
Society often favors extroverts or certain personality types, but success isn't determined by type—it's determined by fit. An introvert in the right role will outperform an extrovert in the wrong one every time.
Career Interests Evolve With Age
Your personality deepens and new functions emerge as you mature, which is why career interests often shift in your 20s, 40s, and beyond. What satisfied you at 25 may not align with who you become at 45.
The Mid-Life Crisis is Actually Personal Development
What people call a mid-life crisis is often the emergence of a dominant function you hadn't fully accessed before, prompting a natural desire to explore new work. This isn't a problem—it's progress.
Forcing Yourself Into the Wrong Role Is Like Writing With Your Non-Dominant Hand
You can accomplish tasks using your non-preferred approach with enough practice, but the work quality suffers and exhaustion sets in. Switching to your natural style makes the same work easy and energizing.
Work That Energizes You Exists
The right career isn't just tolerable—it's something you look forward to doing because it taps into your natural strengths and preferences. This satisfaction is achievable when you choose wisely.
Personality-Career Matching Requires Research
Simply identifying your type is the first step; you must then research actual roles, interview practitioners, and assess whether the work truly resonates with you before making a transition.
All Four Temperaments Are Needed in Organizations
Traditionalists provide structure, Experiencers bring adaptability, Idealists offer creativity and empathy, and Conceptualizers drive innovation. Diverse teams succeed because they combine complementary strengths.
Rank Career Options Against Your Core Values
After identifying suitable careers for your type, prioritize them by asking which one you'd do for free if money weren't a factor. This question cuts through noise and reveals your authentic passion.
Know Your Weaknesses as Well as Your Strengths
Understanding your blind spots and potential pitfalls allows you to prepare for them and explain to employers how you mitigate these challenges. Self-awareness builds credibility.
Skills Inventory Strengthens Your Job Search
Document the specific skills required for target roles and map your past experiences to those skills. This practice helps you identify natural capabilities and craft compelling candidacy arguments.
It's Never Too Late to Change Careers
Whether at 30, 45, or 60, career transitions aligned with your personality type can be the most fulfilling years of your life. An 'encore career' pursued authentically beats decades of misalignment.
Your Teens Are Too Early to Lock In Career Choices
Traditional education forces career planning before personality has fully developed. Recognizing this allows you to hold career decisions more loosely and stay open to evolution.
Personality Traits Solidify Early, But Functions Emerge Over Time
Your core temperament develops by age six, your dominant function becomes clear by 12, but your full personality expression doesn't mature until your 25s-50s. Life stages matter for career timing.
Choose Careers That Can Grow With You
Select roles and fields with flexibility to evolve as you do. A career with room for progression, specialization, or reinvention prevents the need for complete switches later.
Interview Practitioners Before Committing
Talking to people actually doing the work reveals realities that job descriptions and websites hide. This due diligence prevents costly career mistakes based on romanticized assumptions.
Your Personality Type Is Your Career Compass
Using MBTI as a decision-making framework eliminates guesswork and generic advice. It provides a reliable compass for navigating career choices at any life stage.

Expert analysis

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 is a career-planning guide that uses personality typing to help readers align their work with their natural temperament and strengths. It teaches you how to identify your personality type through the Myers-Briggs framework and use that knowledge to find careers where you'll thrive rather than struggle.

How does the Myers-Briggs Type Indicator help with career selection?

The MBTI identifies your four-letter personality type, which falls into one of four temperaments and reveals your dominant function. Each combination points toward career fields and roles where your natural approach to work will be an asset rather than a liability, increasing satisfaction and performance.

What are the four temperaments explained in the book?

The four temperaments are Traditionalists (who value stability and order), Experiencers (who seek adventure and adaptability), Idealists (who pursue meaning and personal growth), and Conceptualizers (who drive innovation and strategic change). Each temperament has distinct strengths and ideal work environments.

Can you change careers if you're already well into your career?

Yes, absolutely. The book emphasizes that it's never too late to transition to a career better suited to your personality type. These transitions, called 'encore careers,' can often be the most fulfilling years of your life when pursued authentically.

Why do career interests change over time?

According to the book, your personality develops in stages: core traits by age six, dominant function by age 12, and full personality expression between ages 25-50. As new functions emerge, your interests naturally evolve, which is why a career that fit at 30 may not fit at 50.

Is there a 'best' personality type for success?

No. The book explicitly states that all personality types can be equally successful. Success comes from aligning your work with your personality type, not from having a particular type. Working against your nature is what creates struggle.

How do I find the right career using this book's approach?

First, identify your personality type and temperament. Then list recommended careers for your profile and rank them by genuine interest. Research those roles through interviews with practitioners, document relevant skills, and ask yourself which job you'd do for free. This process reveals your authentic fit.

What does it mean if your personality type points to multiple career options?

Multiple options are normal—your personality type provides a framework, not a single answer. Your role is to narrow those options through self-reflection, research, and conversations with people in those fields to discover which one genuinely excites you.
