People are optimization functions. Trying to define it as happiness or whatever other complex formula won't work because it quickly goes meta. Its output becomes just one of your inputs. I know that "doing what you want to do" does not seem like a useful answer to that question, but I think the problem is more in the question than in the answer.
We have these huge computation machines in our heads and we're provided with results like "I want to write a novel" based on earlier inputs and with practically all computation happening subconsciously.
Also, I don't thing you would have such a nice list of accomplishments without a laser focus. By keeping it pointed around the same direction you can achieve more in that area compared to others (because strong flashlight can provide comparable amount of energy to the same point during long enough time), but.. back to the first point (achievements are just another input)
