When the good times come around, they gallup in like wild horses. You just try to stay on them for as long as you can. And when they throw you off, you just wait in the shade until they come around again.

Life at its noblest leaves mere happiness far behind; and indeed cannot endure it. Happiness is not the object of life: life has no object: it is an end in itself; and courage consists in the readiness to sacrifice happiness for an intenser quality of life.

If you want to live a happy life, tie it to a goal, not to people or things.

What do you want meaning for? Life is desire, not meaning.

Give a man health and a course to steer, and he'll never stop to trouble about whether he's happy or not.

Even if you're happy with the life you've chosen, you're still curious about the other options.
