There’s a great 1995 article by David Myers and Ed Diener: “Who Is Happy?”
“In study after study, four inner traits mark happy people: self-esteem, a sense of personal control, optimism, and extraversion.”
How are you doing on:
- personal control (do you generally feel in control of your life?)
- optimism (do you generally believe the future will be even better than today?)
- self-esteem (do you generally respect your actions? [or this question])
- extraversion (do you generally make a point to meet with friends?)
Each of these traits is actually acquirable and increasable, which is the most interesting part to me.
