I think it's because I moved from Employee to Contractor, to Consultant/Occasional Contractor before I really got deep into building products that it never seemed like I was in a particularly scary place.
I was already spending several months at a time voluntarily without work, and taking contracts when I needed to. The only real difference was that instead of travelling and rockclimbing full time during those breaks, I was parking it in one spot with the laptop and writing code. And I guess I started referring to those consulting gigs as "bootstrapping".
That might be a good path to look into if you want to make the transition from "guy in a cubicle" to "dot-com thousandaire". There's plenty of room to take it slow.
