A friend sent me a a blog post on happiness.

I distrust what any one person says about something as subjective as happiness. I would rather they show up with a slew of data from many people and say "let's try to make sense of this".

1. How do we measure happiness?
   He doesn't propose a metric
2. How do we make ourselves happy?
   He says it's not just drugs in our brain, that we have to feel some kind of accomplishment.
   While I agree with him, a bunch of drug addicts seem not to.

From what I know of neurochemistry, the drugs really matter. However, habituation to drug levels means that we need to cycle on/off drugs. Perhaps this is the root of needing downs to define the ups?
