Farming is a pretty big thing though, if you want to get into that it might be better off buying property and slowly turning it into a smallholding. Or work at a farm as a farmhand.

Anyway, not parent commenter specifically, but if you're in a situation where you have loads of money but don't know what to do with yourself, volunteer work is always an option, and there's loads of things you could do, be it formal volunteer work (e.g. homeless shelters, retirement homes) or informal (set up IT classes at your local library, go around your neighbourhood and pick up trash, pick up a conversation with a random lonely stranger)
