Here's what I learned: You don't have to cure cancer to solve a big problem. You don't need a tech startup. You don't need venture capital. You need to see a problem clearly. Then build something that solves it. I saw lonely people. I built a place for them to gather. I gave them a shared hobby. A shared goal. A reason to show up. The best businesses are born by solving problems. The most profitable businesses solve big problems. Loneliness is a big problem. Community is the solution. I just happen to sell Pokemon cards while I'm at it.
