The problem with "make money" is that it's mostly a short-term, proximate motivation. As others suggest, you need to figure out what you want the money for. Starting a business is a long-term proposition, so you'll need to find your deeper motivations.
And note that motivation isn't a static thing; it's a thing you nourish over time. So whatever business you pick, it should feed your motivations. E.g., I know somebody who has run a bookstore for 20+ years. He could do things that make more money, but he loves interacting with customers and talking about books on a daily basis.
One exercise you could do is to write your own obituary. Start by going to Legacy.com. Read a few of the famous-people ones on the front page. Next search for your first name and read a number of those. Leave the good ones open in tabs. Then open up a blank document and start typing yours. Refer back to others as needed, borrowing freely. What in others' obituaries resonates for you? What do you want your life to have been?
