advice to self:

one important factor to happiness? you gotta like yourself, because you spend 100% of your time and life with yourself. there’s nothing you can do to get rid of yourself. so, whatever it is you’re doing, do things that will make you proud of yourself, that will help you to like yourself. be someone you would want to be friends with. be someone you would want to love. whether it’s working out, controlling your temper, getting good grades, being honest, being kind, being patient… do the things that will let you be at peace with who yourself at the end of the day. nothing is worth sabotaging the relationship you have with yourself. not your laziness, not your temper, not your fear, not your anger, not your impatience, nothing. 

but in the case that you do let yourself down, do what any good friend would do, forgive yourself and move on to the next moment, which is a new opportunity to become someone better.
