After decades in the startup game, I've figured out one thing for sure: nobody really knows anything. Not your investors, not your teammates, definitely not you. Your brilliant idea? Could be genius or garbage—there's no way to tell from the desk.

Here's what actually works: stop debating, start testing. Put your concept into the real world. Let it crash into actual user behavior, market conditions, competitive pressure. That collision point? That's where real knowledge lives.

It's messy and it's the only way that matters.
