Laughter is more than just a pleasurable activity...When people laugh together, they tend to talk and touch more and to make eye contact more frequently.

Focus not on doing less or doing more but on doing what you value.

The things that go wrong often make the best memories.

I'm doing a lot of speaking and talking about habits, which is this subject that obsesses me. That's a lot of fun.

When we don't get any treats, we feel depleted, resentful, and angry, and we feel justified in self-indulgence. We start to crave comfort - and grab that comfort wherever we can, even if it means breaking good habits.

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.

Turns out that people who try new things, go new places, learn new skills, etc. are happier. This can be tough, because novelty and challenge also bring frustration and irritation - but if you can push through that, novelty and challenge can bring enormous happiness rewards.
