I enjoy the fun of failure. It's fun to fail, I kept repeating. It's part of being ambitious; it's part of being creative. If something is worth doing, it's worth doing badly

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.

Your unhappiness doesn't help anyone else - and in fact, as I mentioned in another answer, happy people are more altruistically inclined. So happiness is not a selfish goal.

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

Self-awareness is a key to self-mastery

If you always use your stapler in one place, keep it there, instead of thinking that all the office supplies should go in one place. I've moved a lot of things around in my house because of that.

Self-knowledge makes me happy.
