Life is too short to waste any amount of time on wondering what other people think about you. In the first place, if they had better things going on in their lives, they wouldn't have the time to sit around and talk about you. What's important to me is not others' opinions of me, but what's important to me is my opinion of myself.
The only way that we can live, is if we grow. The only way that we can grow is if we change. The only way that we can change is if we learn. The only way we can learn is if we are exposed. And the only way that we can become exposed is if we throw ourselves out into the open. Do it. Throw yourself.
If you want to forget something or someone, never hate it, or never hate him/her. Everything and everyone that you hate is engraved upon your heart; if you want to let go of something, if you want to forget, you cannot hate.
