Any advice you’ve ever heard or given. I linked a great video that I think would be my answer, combined with the “stop caring what other people think about you” and “comparison is the thief of joy” comments below. Just do stuff that you wanna do, don’t compare and don’t care what others say. It’s awesome advice.
The worst part is when people you work with wanna hangout after work because you seem like a pretty interesting person and you have to find a million reasons to avoid doing so lest they find out that when you leave work you become the most boring sedentary person alive outside of agoraphobes.
