Having a great idea can seem overwhelming. Pretty soon, you’re paralyzed.
So create a bad idea. Then, use your bad idea as a premise to make better ones. You’ll shift the problem from “How can I have a great idea?” to “How can I make this miserable thing better?”
Once it a while, a truly stupid idea is just what the world needs. But usually, it really needs the tenth version of that first stupid idea.
The trick is to get moving. So trick yourself.
