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

When I find myself focusing overmuch on the anticipated future happiness of arriving at a certain goal, I remind myself to 'Enjoy now'. If I can enjoy the present, I don't need to count on the happiness that is (or isn't) waiting for me in the future".

I can DO ANYTHING I want, but I can't DO EVERYTHING I want.

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.

The most reliable predictor of not being lonely is the amount of contact with women. Time spent with men doesn't make a difference.

Happiness comes not from having more, not from having less, but from wanting what you have.

You really have to begin by figuring out what kind of person you are. The tip is to really take a look at yourself.
