By the time I fully get into it, it won't matter if I make money at it or not (although I will still have that in mind with external clients). It will be an artistic pursuit and a form of stress reduction therapy.
Think of the concert movie Pink Floyd at Pompeii. That's a Grail level event and a permanent record of a time and place when one of the greatest bands of all time was fully in tune. They didn't even have a single audience member, no Rolling Stone interview, no music "critics" in tow, just the movie/music crews, the amphitheater, and the sky above. But they were creating art.
