What you see is filtered through your beliefs. You rarely see "reality." You see your version of it.
You can have, be or do, anything you want.
If you don't go for your dreams, who will?
If you aren't happy with yourself, find a way to be victorious over yourself.
The best way of become forgiving is to feel gratitude.
Nonviolent Communication by Marshall Rosenberg is a great book teaching a compassionate way to talk to people even if you (or they) are angry.
