One thing that has made me a much more well-adjusted person is a clip I once saw of Hank Green saying that anyone can be in amazing shape as long as being in amazing shape is one of their top three priorities.
(This is obviously a generalization that isn't true for everyone. But it is true for most people and I'm proceeding from there.)
This "top three priorities" framing has genuinely reduced my tendency toward jealousy and self-comparison a lot. Now when I feel envious of someone’s spotless, aesthetic home, I think to myself, “Having a spotless, aesthetic home is probably one of their top three priorities. It’s definitely not one of mine, so I shouldn’t expect my home to look like that.”
Or when I see an influencer with a body that takes a ton of work to maintain: “Maintaining that body is obviously one of her top three priorities, because it’s her livelihood. My livelihood is my brain, so I’m never going to prioritize my body like that.”
It also helps me to identify areas that I actually DO want to prioritize more. I realized in recent years that my envy for my friends who prioritized writing more than I did was NOT going away, so I started to prioritize writing more. (Not top three, but higher priority than it has been in the past.)
