Thanks for writing this — the anxiety we all face as we age is crazy. I am 30 and I felt all those things you mentioned in your article because of the mental goals I set for myself that I had not yet achieved. So I let those goals that I could not control go and now I focus on the ones I can control. It’s the best way forward. Life is unpredictable that way we just gotta roll with the punches. If you can master that at 21 then you’ll be set for life. Well done on publishing something on Medium — that in itself is an achievement on its own.
