Happiness comes not from having more, not from having less, but from wanting what you have.

Feelings follow actions. If I'm feeling low, I deliberately act cheery, and I find myself actually feeling happier. If I'm feeling angry at someone, I do something thoughtful for her and my feelings toward her soften. This strategy is uncannily effective.

Flawed can be more perfect than perfection.

Knowing what you admire in others is a wonderful mirror into your deepest, as yet unborn, self.

Nature is impersonal, awe-inspiring, elegant, eternal. It's geometrically perfect. It's tiny and gigantic. You can travel far to be in a beautiful natural setting, or you can observe it in your backyard - or, in my case, in the trees lining New York City sidewalks, or in the clouds above skyscrapers.

Don't let perfect be the enemy of good.

To eke out the most happiness from an experience, we must anticipate it, savor it as it unfolds, express happiness, and recall a happy memory.
