...I mowed lawns and washed cars. Then, when I got to high school and found out I could get school credit for doing essentially the same thing I was doing building models by taking jewelry and metal smithing classes, I said - "sign me up". Then I got into my first scholastic spring art show, made money selling my stuff, and I said - "sign me up AGAIN!" And again, and again, and again.
My art teacher never knew until I told him during my senior year that I had been spending all of the money I was making selling jewelry on model airplanes.
