"What is a truly reliable source of positive emotion?" The answer is that people experience positive emotion in relationship to the pursuit of a valuable goal. Imagine you have a goal. You aim at something. You develop a strategy in relationship to that aim, and then you implement it. And then, as you implement the strategy, you observe that it is working. That is what produces the most reliable positive emotion. . . .
This implies something crucial: no happiness in the absence of responsibility. No valuable and valued goal, no positive emotion.
