I don't really remember, that was a long time ago in a galaxy far, far, away.
When computers started becoming available for less than the price of a house, I could tell I wanted to work with them. Got tossed out of the house as a teenager, and had to work for a living, so I couldn't afford anything to do with computers for quite a few years - they were still many thousand dollars for a basic system at the time.
Eventually I managed to save enough coin to pick up a used computer system. Shortly after that I started doing computer work on the side, and a year or so after that I quit my real job and went into computers full time.
Since then, there's been the occasional lean time, but for the most part, I've gotten paid to do what I love.
With the added benefit of hindsight, I can look back and realize that I would probably have been just as happy as a teacher... but that's ok. Maybe if computers start programming themselves, I'll fall back on that.
