A few years back I gave someone the exact morning routine that had, for a while, turned my own days around. Wake early, journal, cold shower, no phone for first two hours. It was practically scripture to me at that time.
He tried it for two weeks and told me, gently, that it made him miserable. I had handed him a system built around a body clock that was not his. The routine that fit me pinched him.
That small failure is more or less the whole of a line Carl Jung wrote in his 1931 essay “The Aims of Psychotherapy”:
“The shoe that fits one person pinches another; there is no universal recipe for living. Each of us carries his own life-form within him, an irrational form which no other can outbid.”
His point was simple. You have to become who you are, rather than wearing a borrowed template, however well it fits someone else.
A quick note before I go further: I am not a psychologist or a therapist, just someone who reads this stuff and thinks about it a lot. What follows is reflection, not advice, and the studies I mention here are findings from particular groups of people, not settled science or rules that apply to everyone.
Jung meant the shoe as a figure of speech. Then, decades after his death, some researchers made it literal.
The Weizmann Institute’s Personalized Nutrition Project tracked the blood sugar of 800 people across more than 46,000 meals. The same food could send one person’s blood sugar climbing while barely moving another’s.
The lead researcher, Eran Segal, put it plainly. Segal said that “The huge differences that we found in the rise of blood sugar levels among different people who consumed identical meals highlights why personalized eating choices are more likely to help people stay healthy than universal dietary advice.” Identical shoe, two very different feet. What works for one person’s body is not automatically going to work for yours, and no chart on a cereal box knows the difference.
I find that clarifying rather than depressing. It means the diet that did nothing for you, the schedule that wrecked your week, the productivity system everyone swears by that left you frazzled, may not be a personal failing. It may just be the wrong shoe.
Jung’s word for becoming yourself was individuation. Modern psychology has a less romantic term for a slice of the same idea: self-concordance, meaning goals that line up with your own interests and values. In Kennon Sheldon and Andrew Elliot’s work, those goals get pursued with more effort and are more likely to be reached. Reaching them also brings more lasting wellbeing than goals chased out of guilt or outside pressure.
Set that against Jung’s second sentence, about the life-form each of us carries within, and they rhyme. A goal borrowed wholesale from someone else, or adopted because you felt you should, sits in you like a shoe half a size off. You can walk in it. You just will not walk far, and you will not enjoy the walk.
Viktor Frankl, writing from a very different tradition, landed somewhere close. In Man’s Search for Meaning, he held that everyone has a specific mission in life, a concrete assignment that no one else can carry out in their place. Three thinkers, three vocabularies, one instinct: the thing that is yours cannot be outbid by anyone else’s version of it.
The pressure to wear everyone else’s shoes
Jung did not have a phone that served him a highlight reel of other people’s lives before breakfast. We do, and I think it makes his warning harder to follow.
A 2025 study in Frontiers in Psychology looked at young adults and the habit of measuring yourself against people who seem to be doing better. That habit helped explain the link between heavy social media use and both lower self-esteem and more depressive symptoms.
That is the modern machine for trying on other people’s shoes all day. You scroll, you see a life that looks like it fits its owner beautifully, and you wonder why the same outline pinches you. The Jung line is a quiet corrective. There is no universal recipe, and the fact that a way of living suits someone else tells you almost nothing about whether it will suit you.
None of this is an argument for ignoring good advice or refusing to learn from anyone. My friend was right to try my routine. He just had to notice, quickly, that it was not his, and let it go without treating the mismatch as proof that something was wrong with him.
The useful move is not to reject every template. Treat each one as a fitting, not a verdict.
No one can hand you the recipe, and that is less a burden than a release: the shape of a life that holds is yours to work out, by trial and error, over time.
If any of this is landing closer to home than it is interesting, whether that is the comparison spiral or a sense of living a life that never quite fits, talking to a good therapist is worth far more than any quote or article.
