What do you like to do in your free time? Work on your car? find a field that you can work with your hands, but not working on cars. Just an example. Take an aptitude test, it could spark interest. Might surprise you!
Aptitude test would be interesting. I have done everything from calculation pump sizes and fluid flow to driving tractors and welding. would be interesting to see what an aptitude test would say. I will report back if I take one.
