It would be fun to start a business and interject it into the home buying and selling process. I could write articles about how real estate agents must have my product to succeed and give them useful advice and after I collect real estate listings from them I can charge them for advertising.
I can tell them they will fail if they don’t use my product because my product is what consumers really want and I should know because I know. Oh wait that has already been done. Never mind. Have a nice day.
