I graduated a 2yr votech course with 1400+ hours of classroom and hands-on instruction on Farm Eq. Repair in 1966. Went to work at a Eq. dealer as a welder, moved up to mechanic on FE, asked for a raise of 25cents, got a nickel to $2.75. Stuff that, the wife (and I) (+ the 8mo old) moved to Mississippi. Went to work there for $2.15 an hour, could work all the hours I wanted (no OT). Since then, we have raised 2 kids (no college),while working in the national service departments of 2 major FE manufacturers, several dealerships, a major trucking Co.,and I currently assemble machinery in a manufacturing plant; 13 years ago I started my own business-repairing mowers- on the weekends & weekday evenings. During the layoff in 09 & 10, it became full time for 15 months. Contracted out some repairs to 3 other guys doing it part-time who also weren't working.
I define being mechanically adept as: 1. Knowing when you don't have the knowlege or ability;stopping and asking someone who does. 2. Learning something new every day; even that you were wrong about something counts.
I have never done anything in my life that I didn't think someone else could do better; I would give myself a 6 or 7 overall.
P.S. I was lucky enough to receive some formal vocational training and those two years set the course for my life. I am now training young men at the plant, passing on the benefit of that experience.
