“Choose to be optimistic, it feels better.”
“Pessimistic" is a word for "realistic" that optimists use to make themselves feel better (about their unrealisticness).”
“In life, if you want to be happy, choose to be optimistic.”
“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.”
“. . . 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. ”
“In the long run, the pessimist may be proved right, but the optimist has a better time on the trip.”
