happiness

reading some articles this morning,here is a quote:
Experts have figured out that the brain has no ability to actually predict your emotional reaction to life changes that haven't happened yet. In other words, you physically do not know what you want. The act of sitting around pondering it is apparently what fucks you up.
This may be why studies show friendships, altruism and religious practices bring happiness. It may be that taking the focus off your own happiness is what makes happiness possible.
