That article was a little more geared toward people who have no alternate income to sustain themselves. That's not really me. I've got a little money coming in from my freelance consulting and my sites, so I won't starve. It's looking positive that I'll have a book contract soon, and the publisher's marketing people think it could be huge. I'm looking into coaching high school volleyball again as well (I coach the more interesting, more competitive junior Olympic ball now, as organized under USA Volleyball). Bottom line is that I'll have lots to do, and it will mostly be things I like to do.
There is of course the risk that I'll have negative cash flow, for who knows how long. The upside of this though is that .NET jobs are plentiful in my area, and at some point later in the year, having a book to your credit might not make you rich, but it's a nice touch that few developers have on their resume.
All told, I think there are a lot of opportunities, I just have to accept that living the J-Pizzie lifestyle will be a bit less extravagant than perhaps I'm used to, for the time being.
