The Evolution of Personal Comparison: Jordan Peterson’s Philosophy on Self-Improvement
The Origin of This Powerful Quote
Jordan B. Peterson, a Canadian clinical psychologist and professor, articulated one of the most frequently cited pieces of self-help wisdom in contemporary culture with his statement, “Compare yourself to who you were yesterday, not to who someone else is today.” This deceptively simple maxim emerged from decades of psychological practice, academic research, and Peterson’s own philosophical musings about human potential and suffering. Peterson’s presence expanded across social media, podcasts, and mainstream media outlets beginning around 2016-2017. The quote resonated deeply with millions of people grappling with anxiety, depression, and the relentless social comparison that characterizes life in the age of social media. What makes this particular quote so powerful is its directness. It cuts through the noise of self-help platitudes to address a fundamental psychological truth. Throughout his career, Peterson observed that comparing ourselves to others breeds misery. Comparing ourselves to our past selves, however, breeds meaningful growth.
Peterson was born in 1962 in Edmonton, Alberta, to a middle-class Canadian family. His father, Walter, was a high school English teacher and lay theologian. His mother, Beverley, was a school librarian. Both professions were intellectually rigorous and shaped young Jordan’s early understanding of the power of ideas and language. Peterson has described himself as an anxious and somewhat isolated child, prone to bouts of depression that would follow him into adulthood. This personal struggle with psychological darkness would later become central to his worldview and professional work.
He earned his bachelor’s degree in political science and psychology from the University of Alberta in 1984. He then pursued graduate work at McGill University in Montreal, where he earned his PhD in clinical psychology in 1991. His doctoral dissertation focused on the neurochemistry of aggression and dominance hierarchies in lobsters and other creatures. This research interest seems eccentric on the surface. However, it would become foundational to his later controversial claims about human nature and hierarchical structures in society.
Compare yourself to who you were yesterday
Throughout the 1990s and 2000s, Peterson established himself as a rigorous academic clinical psychologist at the University of Toronto. He taught there for decades and developed a devoted following among students. They appreciated his intellectual seriousness and his willingness to engage with difficult philosophical and psychological questions. He published academic papers on topics ranging from aggression to depression. His clinical practice earned him a reputation for helping patients navigate genuine psychological crises. During these years, Peterson developed the core ideas that would later appear in his bestselling books. He believed that life inevitably involves suffering.
He held that meaningful existence requires responsibility and struggle. He insisted that individuals must take ownership of their own improvement rather than blaming external circumstances. These ideas were informed by his readings in Jungian psychology, existentialism, Christian theology, and mythology—an unusual combination. It gave his work a distinctive philosophical flavor. Importantly, Peterson was not primarily known as a self-help guru during this period. He was a serious academic attempting to construct a comprehensive theory of human psychology and meaning.
The quote about comparing yourself to who you were yesterday gained prominence as Peterson transitioned from academic obscurity to cultural prominence. This shift occurred particularly following the publication of his 2018 bestseller “12 Rules for Life: An Antidote to Chaos.” The book became a phenomenon, especially among young men. Peterson became a polarizing public figure. Some celebrated him as a voice of intellectual courage. Others condemned him as a reactionary figure promoting troublesome ideas about gender and hierarchy. Interestingly, the quote itself doesn’t appear verbatim in his published books in a prominent way.
This fact speaks to how internet culture has crystallized and simplified his ideas. The statement likely emerged from various interviews, lectures, and podcast appearances where Peterson repeatedly discussed the dangers of social comparison. He highlighted the psychological toll of measuring oneself against others. Peterson was essentially translating decades of clinical observation and psychological research into an accessible aphorism. This reduction, perhaps, did not distort his underlying philosophy about human psychology.
Why This Mindset Changes Everything
One lesser-known aspect of Peterson’s life informs this particular quote: his ongoing struggle with depression and his openness about seeking help. In 2019, he revealed that he had suffered from depression for much of his adult life. In 2020, he opened up about his struggles with autoimmune issues. He discussed his controversial use of experimental dietary interventions and medications, including benzodiazepines and antidepressants. This personal vulnerability is crucial to understanding the authenticity behind his advice about self-improvement. He wasn’t preaching from a position of having conquered these struggles completely. Rather, he spoke from hard-won experience with how to incrementally improve one’s life.
He did this in the face of genuine psychological darkness. This context gives weight to his insistence on comparing oneself to one’s past self. It’s not a recipe for complacency. Rather, it’s a framework for recognizing genuine progress. This progress can be invisible when you’re caught in the habit of measuring yourself against others. Those others may be further along their own journeys or operating under different circumstances.
The cultural impact of this quote has been substantial, particularly within online communities focused on self-improvement, productivity, and personal development. It has been shared millions of times across social media platforms. Motivational content quotes it regularly. Self-help blogs and YouTube videos incorporate it into their material. For many people, especially young men who constitute a large portion of Peterson’s audience, this maxim has provided a psychological reframe. It helps them combat the anxiety and depression that often accompanies social comparison in the age of Instagram and YouTube.
