You should try welding. Small investment on an inverter you can do arc welding for small projects at home and grow from there. If you like it you push forward, if not you've lost little money and you can sell the material and is not a total loss. Farming entails much more costs and risks, with all the diseases, pests, cost variations and whatnot. Just a suggestion.

I already have two welders, stick and wire, and do a little work from time to time. They were actually essential tools on our farm. I inherited them when my parents passed.
The farming/homesteading is more about growing our own food. We already buy a substantial amount from local farmers, but we'd like to be more self-sufficient. I prefer my food as fresh as possible.
Cool, keep up the good work
