At 30 years old, had surgery on my ankle and went to trade school because I couldn't work. Grajeeated top of my class and got a job at half my "pre hvac" wages at a union shop changing filters in a corn processing plant. Took 2 weeks to change filters on all the equiptment, then I'd start over again. 11 months later the shop lost the account at the plant, they had no more work for me and we parted ways. Was hired by a refrigeration/light commercial shop 2 days later and was thrown out to the wolves. I've been playing with the wolves for 12 years. It doesn't hurt as much when they bite nowadays.
