You need to like yourself....at least somewhat. Question is....Do you? You also need some more confidence. I mean.....would you like to be around someone who is constantly putting themselves down? (sure at first you might want to help them....but after awhile it gets old!) Until you are happy with yourself at least somewhat.....your not really gonna be good at making others happy. At least not the way you want to. So no matter what age you are.....this advice applies. YOu need to break the cycle. Do something for you. Do something that makes you happy. Enjoy life...cuz we only go around once. And eventually ...Im sure someone will see something in you.....that they think is amazing. But how can they if you don't have the confidence to let your true self show?
