The absence of feeling bad isn't enough to make you happy; you must strive to find sources of feeling good

Happiness can seem like an abstract, transcendent notion, but in fact, I found that getting enough sleep (very important!!), getting exercise, not letting myself get too hungry, not letting myself get too cold (I'm a person who is always cold), made a big difference. Partly because I felt happier, partly because feeling physically comfortable makes it easier to keep other difficult happiness-boosting resolutions like biting my tongue.

It's true that people do assume that people who are critical are smarter than people who are uncritical.

Act the way you WANT to feel.

One of the things that you see ancient philosophers and contemporary scientists agree on is that strong relationships are a key to happiness, maybe the key to happiness. People who have more strong relationships in their lives just feel happier.

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

There's a kind of magical thinking about these kinds of things. Throw away those bad photos before the "magic" attaches to them, so the good ones stand out.
