Definitely the pinball machine mogul, even if I make less money. Why?? It's "leveragable" and it makes money even when I'm not working. This is the perfect type of business that we should all strive for.
What do I mean by leverageable? I mean that it can be expanded with only a small amount of time. Unlike a CPA, doctor, or lawyer who has to work more in order to make more. A leverageable market/product means that the amount of money you make are capped by how many hours are in the day. Will you need to work more if you have 1,000 pinball machines vs 100. Probably. But you're not going to have to work 10x more! And if you find the right management you can then actually work less, not more.
