The Evolution of Personal Comparison: Jordan Peterson’s Philosophy on Self-Improvement
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. The quote gained widespread traction beginning around 2016-2017, particularly as Peterson’s presence expanded across social media, podcasts, and mainstream media outlets. It 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 that Peterson had observed throughout his career: that comparing ourselves to others is a recipe for misery, while comparing ourselves to our past selves is a recipe for 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, while his mother, Beverley, was a school librarian—both intellectually rigorous professions that 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, 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—a research interest that seems eccentric on the surface but would become foundational to his later controversial claims about human nature and the immutability of hierarchical structures in society.
Throughout the 1990s and 2000s, Peterson established himself as a rigorous academic clinical psychologist at the University of Toronto, where he taught for decades and developed a devoted following among students who 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, and his clinical practice earned him a reputation for helping patients navigate genuine psychological crises. During these years, Peterson was developing the core ideas that would later appear in his bestselling books: the notion that life inevitably involves suffering, that meaningful existence requires responsibility and struggle, and 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 that 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, 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, and Peterson became a polarizing public figure—celebrated by some as a voice of intellectual courage and condemned by others 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, which 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 and the psychological toll of measuring oneself against others. What Peterson was essentially doing was translating decades of clinical observation and psychological research into an accessible aphorism—a reduction, perhaps, but not a distortion of his underlying philosophy about human psychology.
One lesser-known aspect of Peterson’s life that informs this particular quote is 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, and in 2020, he opened up about his struggles with autoimmune issues and 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 but rather from hard-won experience with how to incrementally improve one’s life 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 but rather a framework for recognizing genuine progress, which can be invisible when you’re caught in the habit of measuring yourself against others who 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, quoted in motivational content, and incorporated into self-help blogs and YouTube videos. For many people, especially young men who constitute a large portion of Peterson’s audience, this maxim has provided a psychological reframe for combating the anxiety and depression that often accompanies social comparison in the age of Instagram, YouTube
