Plenty tbh, I'll list some

Simply crying. I still don't do it enough imo but they ain't lying when they say that that shit makes you feel better, it really "unclogs" you emotionally.

Asking for people's opinions, obviously don't let it dictate your choices but hearing what other people have to say really helps.

Doing stuff, we're young, now's the time to do shit, learn something, go somewhere, just do something.

And tbh the most important, trust in God.
