Getting control of stuff makes people feel like they have more control over their lives - maybe irrationally, but it's one of these psychological truths.

Negative emotions like loneliness, envy, and guilt have an important role to play in a happy life; they’re big, flashing signs that something needs to change.

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.

One of the findings that really interests me is that, although we think we ACT because of the way we FEEL, we often FEEL because of the way we ACT. So an almost uncanny way to change your feelings is to act the way you WISH you felt.

Do good, feel good; feel good, do good.

Self-knowledge makes me happy.

I think the big myth about habits, and happiness too, is that there's somehow a magic "one size fits all" solution. That, "If it works for you it's going to work for me," and it's just a matter of figuring out what that habit would be, whether that's do it first thing in the morning, or start small, or do it for thirty days, or give yourself a cheat day.
