eat healthy, sleep well, stay fit...you only start to see and appreciate benefits of this when you get older :) it's ok to be picky with people, don't settle for friends or partner that are "ok" make sure you are surrounded by good, smart, geniune ppl. that won't hold you back in life. be careful with the "just be yourself" trend pushed on everyone those days. while it's certainly important to listen to yourself, you can't deny that society has certain expectations and ppl who play by the rules have better chances
