I think happiness can be measured through self-examination. I've been trying this now, for the past four weeks. I take the following list:

POSITIVE FEELINGS

**future
faith
hope
optimism
trust

**present
awe
calm
confidence
ecstacy
flow
joy
passion
pleasure
zest

**past
contentment
fulfillment
pride
satisfaction
serenity

NEGATIVE FEELINGS

**future
dread
fear

**present
agony
angst
anxiety
boredom
depression
jealousy
dysphoria
discomfort
fear
frustration
hate
sadness
stress
tension

**past
dissatisfaction
embarassment
guilt
regret

Once a week, I score myself from 1 to 10 on every emotion, and assess what needs help on.

So far, I think it's working out well. I was able to assess problem areas and fix them over subsequent weeks. In addition, it's always surprising to myself how extreme some of my scores get.

It's in an excel spreadsheet right now, let's see how long I stick with this.
