I have found through multiple experience not to do a hobby as a job. I used to enjoy working on bicycles, then I worked in a bike store, now I can't remember the last time I put air in my tires never mind tuned it up. I used to love riding my bike everywhere, then I got a job as a bike courier, now I never ride my bike. I used to enjoy messing around with the computer, breaking things and fixing things, then I got a job fixing peoples computers and you guessed it, I hate working on computers now, I have a dvd-rw that we got for xmas that we have yet to install in our tower.
I have learned that I hate mindless repetitive stuff and dealing stupid people.
