You'd probably like this guy. Like you, he has brains. He's a man of many talents. Has a pretty decent machine shop. 3 lathes, milling machines, etc. For business, he operates a towing service but has a number of hobbies. One of his hobbies is his 5 year old grandson. When the boy was 2 years old grandpa built him a 23 hp rat rod car. Don't think I had a tricycle when I was 2. This year for Christmas grandpa built him a diesel powered bulldozer. Here's a link for some of the work he's doing on the old crane.
Also, here's links to the boy's car and bulldozer.
