Yeah, it's definitely a separate set of skills, and probably not one that typically fits personality-wise with the typical computer guru set. I was self-employed for a couple decades, and while I usually didn't go hungry because it paid well when I was working, the work that walked in the door on its own never got me ahead either.

No one's fault but my own, but I should have realized a lot sooner that real success would require a lot more proactive "sales" effort; and that if I wasn't willing to do that, I needed to go work for someone else a lot sooner than I finally did.
