Most people assume their personality is fixed—that being anxious, introverted, or disorganized is simply “who they are.” But research reveals a different truth: Personality traits are malleable patterns of behavior that we can intentionally change through consistent practice. In Me, But Better (2025), Olga Khazan explores the science behind personality change and her own year-long experiment to transform her neurotic, introverted temperament into something more extroverted, agreeable, and emotionally stable.

The key to transformation, she shows, lies in “faking it until you make it”: practicing behaviors associated with the traits you...

Me, But Better Summary What Is Personality, and Can It Be Changed?

Understanding personality change begins with learning what personality is and whether its fundamental characteristics can be modified. In this section, we’ll explore the scientific framework psychologists use to measure personality and examine the evidence that personality traits are malleable. We’ll also reveal how genetic and environmental factors interact to create opportunities for you to intentionally change your personality.

The Big Five: A Framework for Measuring Personality

Personality refers to the relatively stable patterns of thoughts, feelings, and behaviors that characterize how a person typically responds to life situations. While personality might seem like an abstract concept, psychologists have developed systematic ways to measure and discuss it. The framework Khazan uses throughout her book is the “Big Five” model, which organizes personality patterns into five core dimensions. The Big Five model emerged from a statistical analysis of how people describe themselves and others, and it identifies five broad categories that seem to capture much of the variation in human personality.

Me, But Better Summary Why Change Your Personality?

Knowing that personality change is possible doesn’t automatically make it worth pursuing. This section examines how personality traits influence life’s outcomes and explores how changing these traits can help people live more authentically.

Personality Traits Influence Life Outcomes

Khazan explains that personality traits aren’t just neutral characteristics—they’re powerful predictors of how your life will unfold. Research reveals that personality functions like a set of tools: Some configurations help you build the life you want, while others create obstacles to happiness and success. People with certain trait combinations report higher life satisfaction, achieve better career outcomes, maintain stronger relationships, and enjoy better physical health. But those with other trait profiles face disadvantages across these same areas. Personality traits influence how you respond to opportunities, handle setbacks, build relationships, and pursue goals.

For instance, Khazan explains that high levels of extroversion strongly predict happiness, not because extroverts are “better people,” but because extroverted behaviors—socializing, speaking up, engaging actively—create...

Me, But Better Summary How to Change Your Personality

Once you’ve identified which personality traits align with your values, the challenge becomes actually developing them. This section explores the core mechanism of personality change, why the process necessarily involves discomfort, how you can design your environment to support new behaviors, and specific strategies for developing each trait.

“Fake It Until You Make It”

Khazan explains that the fundamental principle underlying personality change is simple: You strengthen or weaken personality traits through repeated practice. This “fake it until you make it” approach recognizes that your personality patterns emerge from habitual ways of thinking, feeling, and acting rather than from fixed characteristics. This runs opposite to what most people assume—namely, that personality determines behavior. For instance, you might think you avoid parties because you’re introverted, but research reveals the reverse: Consistently engaging in introverted behaviors, like avoiding social interaction, reinforces introverted personality patterns.

This creates a powerful feedback loop you can use to change your personality. Khazan reports that when you consistently act in ways that...

Shortform Exercise: “Fake It Till You Make It”

Khazan contends that to change your personality, you have to understand which personality traits you want to develop and create a specific plan to practice behaviors associated with those traits. This exercise helps you identify concrete actions you can take consistently to strengthen the traits you want to develop.

First, consider your current personality profile. Which of the Big Five traits do you feel limits your life satisfaction or prevents you from achieving your goals? (Do you wish you were less anxious or neurotic? More social or extroverted? More organized or conscientious? More cooperative or agreeable? More open to new experiences?)

Shortform Exercise: Connect Personality Change to Your Values

Khazan explains that sustainable personality change requires connecting the traits you want to develop to what matters most to you. This exercise helps you identify your core values and understand how personality traits can serve as tools for expressing those values.

Think about moments in your life when you felt most authentic and fulfilled. What values were you expressing in those moments? Consider values like: connection, creativity, achievement, service, family, integrity, growth, or others that resonate with you.
