199 — Can You Really Change Who You Are? The Surprising Truth About Personality With Olga Khazan

March 31, 2025
Mentally Stronger Amy Morin Olga Khazan

Are you stuck thinking, “This is just who I am?” Think again. Science shows your personality might not be as fixed as you think.

Olga Khazan knows this firsthand. As a journalist and author, she embarked on a journey to change her personality. And now, she’s discovering what she learned.

 
Some of the things we discuss are:
 

  • The five core personality traits and how they shape your life
  • Why science says personality isn’t as fixed as you think
  • The habits and exercises that can help you become more outgoing, less stressed, or more ambitious
  • How Olga’s year-long experiment radically changed her reactions, relationships, and outlook on life
  • Insightful ways to step outside your comfort zone and grow into your best self

 

Key Takeaways:

 

  • Personality traits can be changed; they aren’t permanently fixed from childhood.
  • Engaging in new activities and social experiments can lead to significant improvements in personality traits.
  • Journaling, mindfulness, and structured habits like to-do lists can greatly aid in cultivating desired personality traits.
  • High levels of extroversion and conscientiousness, as well as low levels of neuroticism, are correlated with happiness and long-term success.
  • The ability to change how we react to stressors is more attainable than altering life circumstances.
