All of the above. Or almost. And being a jack of all trades really works for me. In fact, that's what I think my focus really is - picking up new skills, figuring stuff out with an obsessive drive to know how everything works. And having done this all my life, I've gotten pretty good at it. I was never happy doing just one thing for any length of time. Now I do them all (consultant with multiple clients doing very different stuff for each, plus my own projects). First time I really feel like I'm enjoying my work.
