I work according to need. My business makes enough to sustain me, and more money wouldn't make me happier. I'd love to make my product better because that would benefit a lot of people. However I must accept that the work is never done, and that there is no need to rush it. Realistically, I work from 0 to 12 hours a day according to the weather, and how passionate I am about the task at hand. I'd estimate that I work 3 hours a day on average, but it's a wild guess.
