Dan Gilbert mentioned affective forecasting and how we tend to be biased in predicting positive outcomes. My question to him is how does happiness relate to affective forecasting? If our beliefs about what will make us happy are wrong, then what do we need to change? Should we bother predicting our happiness or "go with the flow"? To what point do we separate desires from reality or just be more realistic about our capabilities? Doesn't taking the extreme of being realistic curtail innovation? How can we dream big without feeling discouraged if the fruits of our labor don't work out?
