Five things separate businesses that make money from businesses that own you.

Most businesses fail because they pick industries that are missing 5 key components. Leverage means as often as possible you can use other people's money, not yours. Velocity of capital means how quickly do you get the money back after you have put it in. The Lindy Effect is what is the historical likelihood of a business to stay around based on how long it's been in the past. So has the business succeeded for the last 20 years? It's actually more likely to succeed for the next 20. Simplicity means, is it so simple you can explain it to Grandma? If it is, then it's an interesting business. And last is recurring revenue, which basically means, do I have to keep working for every single dollar? Or if I get the dollar once, can I have that dollar continue to come to me in some form or fashion?
