I'm doing multiple things - I didn't want to have all my eggs in one basket, revenue-wise. I'm getting to the point where I may want to refocus on just one avenue again, but the issue of having all income dependent on just one source, then getting shafted, was painful. Diversification was a reaction to that.

I know what you mean about $9k feeling like a lottery win. As I said, I ended up suing, but it's likely going to be years before you get a trial, and assuming you get a judgement, you still have to collect.
