Do you know anyone who is a mechanic or tradesman? They use tools to build or repair things
I do, I have friends and family members that are mechanics. 
My brother wants to be an auto mechanic, but likes many trades. I myself am more book smart
There are several options for schools depending on where you live. Does he like to take things apart and put them back together?
Yes, and as an automotive technician, he has a wide varierty of topics to learn, so he needs to be good at it
The pay is actually quite good for mechanics. Many people are focused on college educations rather than trades.
Yeah, and like college, mechanics still typically need to be certified, which is like a degree in a way
Absolutely. Wouldn't want just any Joe-Schmoe to be fixing brake lines on a car :)
