I just build projects that interest me (websites, apps, games). So far released 62 things, of which 10 made >$10k. It's interesting because you get to do a variety of things, and I don't really mind the unpredictability. Might even like it in a slot machine variable reward sort of way.

Just now I spent 3 months making a game that turned out to be worth $0, but that's part of the process. As long as the project itself is interesting and you learn something from it, it doesn't feel like totally wasted time.
