I think you do the things you enjoy. You do them for you. And that’s good enough.
You need to be yourself, not someone that someone may or may not want u to be.
I think like your course selection this is being over analyzed too. After all no matter how perfect you think you make yourself, there are no guarantees.
Do what you like, make an impact and hopefully you can quantify your efforts.
Be yourself. And some school some where will get a great asset.
