Terry Pratchett: "Inside every old person is a young person wondering what happened."

Life is all about making choices. Always do your best to make the right ones, and always do your best to learn from the wrong ones.

Life is about evolving — don't stay in a situation that's not helping you grow.

Sometimes you have to realize that the world is too beautiful to waste your time being angry or sad when you could be enjoying what life has to offer.
