If you need to come up with a new idea, stop trying to think of the best one. Instead, imagine the worst idea possible: What would be the wrong way to solve this problem? What do our customers absolutely not want? How could we make all of our stakeholders angry? Try to come up with ideas that would get you laughed at (or maybe even fired), and then work backward from there to find new ways of solving the problem. This process, called “wrong thinking” or “reverse thinking,” isn’t always easy to do. You can start by trying to see the problem as a beginner would. What would someone who knows nothing about the context suggest? When you give yourself permission to have bad ideas, you often come up with the best ones.
