Step 1: Think of an idea that you think (or know) that can be monetized in the future. Even if you don’t know exactly how to do it, think of something better than “I’ll just get a lot of users”.
Step 2: Let your startup grow, and do the numbers to see when you’re going to NEED to be profitable. If it gets out of control, it might cost you a lot of money
every month just to keep the thing running. Does that sound like a good business?
Step 3: Profit your ass off. After you do this, then you can retire to your very own Caribbean island and watch South Park all day.
