I actually don't have any FORMAL training in ANYTHING.
I'm a high school dropout.
Spent 5 years as an auto mechanic.
Another 3 as a welder.
2 operating/programming CNC lasers.
And the last 3 years I've headed the fabrication shop where I work.
I started working with 3D in Autocad, and this is where it's led me.
Oh, I only started working with PC's shortly after my son was born, he is now six.

I guess I just get bored and look for something new to learn.
