Pouring out ideas is better for creativity than doling them out by the teaspoon.

The number one resolution that people mention to me as something that's made them happier is - to my surprise - making the bed.

People feel happier when they feel like they're progressing. When they feel like something in their life is growing or getting better.

Step by step, you make your way forward. That’s why practices such as daily writing exercises or keeping a daily blog can be so helpful. You see yourself do the work, which shows you that you can do the work. Progress is reassuring and inspiring; panic and then despair set in when you find yourself getting nothing done day after day. One of the painful ironies of work life is that the anxiety of procrastination often makes people even less likely to buckle down in the future.

The belief that unhappiness is selfless and happiness is selfish is misguided. It's more selfless to act happy. It takes energy, generosity, and discipline to be unfailingly lighthearted.

There's also something about your bed; it's sort of a symbol of yourself and of your marriage, if you're married. Making your bed doesn't seem to be an important thing in a happy life, and yet it can be that tiny foothold into a more orderly life that sometimes people need.

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.
