Jordan Peterson's daily personality building lesson: 'Compare yourself to who you were yesterday, not to who someone else is today'

In a world dominated by social media, instant updates, and constant comparisons, maintaining personal growth can feel overwhelming. Many people struggle with measuring their success or progress because they look at others instead of themselves. Addressing this challenge, Jordan B. Peterson, the Canadian clinical psychologist, author, and public intellectual, offers a simple but powerful daily lesson: “Compare yourself to who you were yesterday, not to who someone else is today.” This principle encourages focusing on self-improvement rather than measuring one’s worth against others.

Self-Improvement, Not Comparison

Peterson’s message highlights that self-improvement is a personal journey. By focusing on one’s own progress, individuals can develop a realistic understanding of growth, celebrate small victories, and stay motivated to improve. Measuring oneself against others, in contrast, can lead to unnecessary frustration, envy, and self-doubt, making it harder to achieve meaningful development. The essence of this approach is about building consistency, accountability, and personal responsibility—principles that Peterson frequently emphasizes in his teachings.

The quote also implies that progress is incremental. Growth is rarely dramatic or instantaneous; it is measured in small steps taken every day. Comparing today’s self with yesterday’s self creates a constructive mindset, where even minor improvements are recognized and reinforced. This mindset fosters resilience, patience, and long-term commitment to personal goals, forming the foundation of sustainable development in both personal and professional life.

A Life Rooted in Psychology and Education

Dr. Peterson is an author, psychologist, and Professor Emeritus at the University of Toronto. Over two decades, he taught highly regarded courses at both Harvard and the University of Toronto, while publishing over 100 scientific papers on topics ranging from personality and creativity to emotion and antisocial behavior. His academic work, including the book Maps of Meaning, examines the psychological underpinnings of belief systems, while his bestsellers 12 Rules for Life and Beyond Order have sold over seven million copies worldwide.

Alongside his wife, Tammy, Peterson has conducted sold-out international lecture tours, sharing insights into mythology and human behavior with hundreds of thousands of people. His online platforms, selfauthoring.com and understandmyself.com, have guided tens of thousands of users in exploring their personalities, clarifying past experiences, and setting goals for the future.

Peterson gained widespread recognition in 2016 when his online lectures and interviews went viral, establishing him as a public intellectual.
