Contemporary research shows that happy people are more altruistic, more productive, more helpful, more likable, more creative, more resilient, more interested in others, friendlier, and healthier. Happy people make better friends, colleagues, and citizens.

It's so easy to wish that we'd made an effort in the past, so that we'd happily be enjoying the benefit now, but when now is the time when that effort must be made, as it always is, that prospect is much less inviting.

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.

I've noticed that a lot of people do much better when all their resolutions are framed as 'Yes.' Not something like, "I'm going to give up French Fries," but something like "I'm going to eat three vegetables every day." "I'm going to hug more, kiss more, touch more." "I'm going to listen to more music." They do better when they frame things in the positive. And I think this is just part of human nature.

Did I have a heart to be contented? Well, no, not particularly. I had a tendency to be discontented: ambitious, dissatisfied, fretful, and tough to please...It's easier to complain than to laugh, easier to yell than to joke around, easier to be demanding than to be satisfied.

Often, if there's something that I want to do, but somehow can't get myself to do, it's because I don't have clarity. This lack of clarity often arises from a feeling of ambivalence - I want to do something, but I don't want to do it; or I want one thing, but I also want something else that conflicts with it.

When I thought about why I was sometimes reluctant to push myself, I realized that it was because I was afraid of failure - but in order to have more success, I needed to be willing to accept more failure.
