I just keep thinking to myself, "here I am working so hard at improving my programming abilities so that I can create more ambitious applications, and this guy is making a small fortune selling a freakin' Bingo card maker."

Its more of a small fortune cookie than a small fortune. Maybe something along the lines of "90% of the important stuff happens outside of the IDE."

On the plus side, it proves what you want to do is achievable, right? Make program, improve lives of customers, get paid for it.

I really appreciate your contributions to this site. Your experience is outside the norm and you put forth the effort to share it. That's valuable.
