Isn't that the truth!
When I was a kid, video games fascinated me, and then the age of personal computers at home began. My first computer was an Atari 400. So I got drawn into the whole computers and programming thing, which led to a career in the IT field.
For for first handful of years, I enjoyed it, but as time went on, I grew to hate it. Sitting in an office building, in a cube, pecking away at a keyboard, and starting at a computer all day got old. Plus, every program ever written does the same basic things - take input, process it, and produce output. After a while, every program and system I ever wrote (and still continue to write) seems like I'm just doing the same boring thing over and over again.
That's probably the curse for 99% of the workforce out there. People get pigeon-holed into working at something they might be good at, but don't enjoy (or in my case, don't enjoy any more).
