It's not enough to have good ideas. You have to be able to act on them. You can't make money directly from the idea of a gadget. You can't be a conceptual house painter. There are no theoretical gardeners. You make actual things of value, or you do not. I am personally too often on the theory side of that theory vs practice fence.
