I want to be an apple tech, where do I begin?

"Sometimes to take a major step foward, you have to completely change direction."

I have a MA in counseling, yet i'm not satisfied with my career. I've loved Macs since highschool (in college I switched to Windows), but have only limited computer knowledge. That being said, I've always enjoyed working on computers (taking them apart, building custom units and such).

I want to work on Apple computers, maybe doing repairs. Where would I begin?
