When I was small, I wanted to be a violinist. Then, a photographer. I wanted to be a photographer for a long time, then hurricane Alica wiped out my mom's apartment while I was in the Navy. She gave me part of the settlement money, and I spent $3500 on an Epson QX-10, and it was downhill from there. I spent decades being distracted by computers, networks, and numerous electronic distractions. Then I fell back in love with photography, tried to do the traditional portrait/wedding studio thing and discovered I really like my own, non-commercial style and want to teach traditional methods as well, but crashed and burned as an art major, so here I am doing IT work again, looking forward to the day when I can once again be just a computer user.
oh, but the story continues. Once, in '85 or so, I was a computer science major and let all my other classes crash and burn so I could stay up all night and day producing 2-3"-thick programs for my comp sci classes when a four-page program would have sufficed. Somewhere along the way, I got caught up in system administration when what I really like in computing is software development. Slowly, hopefully, I'm getting back into the latter. Maybe in a year or two I'll be a developer.
Photography? I've got several friends/acquaintences who manage to keep creative projects afloat and even get gallery shows even though photography's not their main gig. Seems like a good model to me.
