I started at an early age, back in the days when my dad would be out fixing up the old van I'd be out there helping him out by handing him tools as he needed them.
Then I just started playing with stuff and learning the hard way alot of times.
When I was in my young teens I learned that my neighbors would give me money if I mowed their lawns. I used my dads mower of course, so when it broke he would help me fix it. The more times I fixed it the less he helped so I had no choice but to learn.
In high school I took a small engine class where we learned how they work and we had a project where we rebuild an engine. The test was to see if would run. I pulled the rope, and I pulled until I couldn't feel my arm, then the teacher said ok, thats enough, I said one more pull. I pulled again and the little engine sprang to life. It smoked, and made horrible noises but I didn't care because I made it run.
Then I took automotive classes and got pretty good since I bought a junker that needed about an hour of work for every hour I drove it.
Thats when I started looking into the sky and saw airplanes and helicopters flying, and I thought that they were the most awesome thing ever. Sure a boat can float, and a car can drive, and they all have alot of really neat stuff about them, but man, they sure can't fly.
Then I went to airplane mechanic school and three years later I walked out with a liscense to fix from the FAA, and for the past 3 years I have had the honor of being able to fix and maintain some of the coolest machines on earth.
