One of the best days of your life is when you start caring about yourself! Be the best that you can be, when you make a mistake, learn from it, pick yourself up and move on!
Do things because they interest you, not because they make you look interesting! And then take stock in a few months and see if you are not happier, healthier and working on some actual friendships with other imperfect but lovely humans.
Do not go out and look for a perfect personality and duplicate it, be yourself but always your better self!
