I have an uncle with an 8th grade education. He has built his own home (twice) and is an auto mechanic by trade. He has a dozen rental properties, unfortunately in a very poor area, but still. In short, he is the handiest, most self-sufficient man alive.
A few years ago, some FA got ahold of him and wanted to meet. My uncle suggested McDonald's. FA spouts off all sorts of stuff that is basically Greek to my uncle, who manages to get out of McDonald's. On the way home, he notices a pair of riding lawn mowers for sale. He stops, sees that they need work but are in pretty good shape. He gets them for $400 both, takes them to his shop and makes the repairs, sells them within the next week for $600-$700 each.
He tells me this story very humbly and says, "I know I don't know anything about investing, but I think I'm doing all right."
"Uncle Charles," I told him. "Just keep doing what your doing and don't talk to any more of those guys."
