Personally... I think I was born with a mind that literally 'sees' mechanical things and electrons going down wires. I can just look at things and find the issue... rarely do I have to go through a step by step procedure to find the offending part. (This was the reason aircraft mechanics was not for me; the FAA REQUIRES--by law--you to follow the written procedures to the letter).
The other thing for me: I just like running my own show... Was talking to Greg, the guy with the vending machine co... he and I agreed we would drive a forklift at HD before we would work in corporate again.
