I know if I am energized at work, happy at work, feeling like I'm adding value, part of a team, whatever energizes you, that makes me better at home. It makes me a better husband, a better father. Likewise, if I'm happy at home, it makes me a better employee, a better boss.

Life laughs at you when you are unhappy; Life smiles at you when you are happy; But life salutes you when you make other happy.

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

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.

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

Life without enquiry is not worth living for a man.
