There are lots of different forms of Working for Yourself. This is evidenced in the author's last few points, where he seems to equate Working for Yourself with Consulting, or, rather, Working for Somebody Else. My favored form of Working for Myself involves building self-sustaining products that bring in the maximum revenue with the minimum commitment on my part. That means, for example, a product that sells itself without my involvement, is straightforward enough that it doesn't generate many support requests, and stays finished once it's launched. With that sort of business, the author's worry about income stopping when you stop working goes away completely. The whole point is to stop working. State that as the goal from the outset, and you'll be good to go. Quite literally.
