I've come to this same conclusion over the years. I'm a good programmer, probably top 1%, but that means there are a hundred thousand better programmers out there. I've come across some that can do things I will never be able to. I'll likely never be the best at any one thing. But I strive to improve at all the things that matter to me. I even have a spreadsheet titled "better than yesterday" where I track my progress.

Try to be the best version of yourself, not the best in the world. This constant need to compare yourself with your peers and neighbors and edited Instagram models is very unhealthy. It is the exact opposite of the road to happiness.
