Strong, pure, and happy thoughts build up the body in vigour and grace.

There is no physician like cheerful thought for dissipating the ills of the body; there is no comforter to compare with goodwill for dispersing the shadows of grief and sorrow.

Where is the burden which should cause unhappiness or sorrow? It does not exist. If a thing is to be done let it be done cheerfully, and not with inward groanings and lamentations. It is of the highest wisdom to embrace necessity as a friend and guide.

Indigence and indulgence are the two extremes of wretchedness. They are both equally unnatural and the result of mental disorder. A man is not rightly conditioned until he is a happy, healthy, and prosperous being; and happiness, health, and prosperity are the result of a harmonious adjustment of the inner with the outer, of the man with his surroundings.

Criticism and pessimism destroy families, undermine institutions of all kinds, defeat nearly everyone, and spread a shroud of gloom over entire nations.

People who do comedy are always underrated because they make it look so easy.

If you're serious, you really understand that it's important that you laugh as much as possible and admit that you're the funniest person you ever met. You have to laugh. Admit that you're funny. Otherwise, you die in solemnity.

George W. Bush was president through some of the darkest days of our history and yet his optimism never waned. He is optimistic by nature, but he also understood the importance of always communicating a sense that things will get better.

There's a tremendous amount of humor... in very unexpected places.

I like jokes and one-liners. I enjoy entertaining and making people laugh, being the funny man. But when I'm launched into unfamiliar environments I shut down, and as I relax then my character emerges.

Wisdom paints a rainbow in your mind, joy paints a rainbow in your heart, and love paints a rainbow in your soul.

Joy is the best companion, virtue is the noblest acquaintance, wisdom is the cleverest friend, and love is the kindest soul mate.
