“So let us be loving, hopeful and optimistic. And we’ll change the world.”

“My friends, love is better than anger. Hope is better than feel. Optimism is better than despair. So let us be loving, hopeful, and optimistic. And we'll change the world.”

“Hope is a state of mind independent of the state of the world. If your heart's full of hope, you can be persistent when you can't be optimistic. You can keep the faith despite the evidence, knowing that only in so doing has the evidence any chance of changing. So while I'm not optimistic, I'm always very hopeful.”

“Let us hope that we are all preceded in this world by a love story.”

“Love changes things; hope allows us to endure until the change arrives.”

“. . . if there is a way for the world to be transformed for the better, it can only be done by pessimism; optimists will never change the world for the better. ”
