Was working hands on with others who had all the experience you could ask for. Graduated from Spartan School of Aeronautics in 84. They had just acquired a Schwitzer for a monthly course for helicopters. I was like "I'm never going to work on them" So I did not stay another month. 35 yrs later ive been working on them with PHI and with some of the best mechanics you could work with and learn from.
