When I went into university to do chemical engineering, in 1981, I had never even touched a computer. I didn't know until I got there that you could even do computers as a career.
I graduated, and then volunteered as a teacher in Africa for 3 years. I came back to Canada, and then taught English in Japan for 3 years.
But after my first year of university, my family got a computer (a Commodore Vic 20, with 3.5 kB of memory) and I was obsessed from that woman onward.
Leaving Japan, I went back to school and did a diploma in computer science. Unlike chemical engineering, where I dutifully learned things that I was told I needed to learn, I was delighted to have the chance to learn about software, operating systems, databases, graphics, etc. The difference was astonishing, and I found it easy to maintain a GPA just under 4.0.
I have been working as a programmer for more than 25 years, and although it has been stressful at times, the joy is still there. I'm not an artist by any means, but I do feel like a craftsman, and I enjoy the opportunity to continue learning everyday.
