Jim Rogers praises the field of Agriculture and farming-
"More people need to get into farming; otherwise, we won't have any food. The best thing you can do is become a farmer, assuming you know what you're doing. I imagine I'd be terrible at farming, as I know nothing about it and have no experience. That's why I stick to investing."
