Its interesting to hear from someone who's more of a hobbyist programmer. You don't meet so many, mainly I think because once you become half-decent at programming you have access to a range of well paid jobs. Of course as you say, those jobs come with certain conditions that aren't for everybody.

I've often thought of quitting professional programming and it to become a hobby instead. I think sometimes great things come from playing around and working on projects you want to and enjoy working on as opposed to the 'drudgery' of implementing someone else's vision. In my experience although the job has its perks, very few 'real' programmers actually care much about the products they work on. Sometimes they do when they start but it doesn't take long for the pressure of getting something done vs. getting something done you have real pride in generally breaks you eventually.

At the end of the day I think if you can write some code, you are a programmer, whether you are a hobbyist or not. Some of the best developers hack on open source projects and live off very little and they're pretty happy with their lifestyle. A lot of paid-up programmers are in fact more like 'impostors' than these guys.
