I probably would have stuck it out in my 1st career, photography/retouching...or I may have pursued my interest in the sciences and become a chemist/physicist or engineer or some kind.
I'd be doing Chemical Engineering or something, since I was good at that at High School. Seriously, I think that all of my high school years have been a completely waste and wouldve done different stuff now that i think about it.
The title is pretty self-explanatory. Let's say software packages weren't released to the public, or better yet, you didn't know anything about 3D, just weren't interested in it - what would you be doing right now? What kind of job would you have? I'll start first. If not for my discovery of 3D/CGI, I would have a job…
