As a kid I hated the old junk Dad had for us to use and work on. But he made us do it so we did. His reward for us working was to buy us sleds and motorcycles. Junk also, but we had the skills to keep them running.
The mechanical aptitude I gained from that made me a lot of money as a plumber. It has saved me countless thousand$ over the years on repairs to most anything as I didn't have to hire it out.
Fast forward 30 years I now collect antique tractors and implements to fix them up.
I forced my son to work around the acreage and run as a plumbing apprentice with me. He resented it and was the source of many a fight. Off topic but I never would have dreamed of fighting my father like my son fought me. Different times I guess.
He has very little mechanical aptitude and has no interest in it at all.
I lost that battle.
He is 21 & doing well in the animal sciences program at Texas A&M, and wants to be a Veterinarian.
