Avoiding stupidity is easier than seeking brilliance. 
“Inversion is a powerful tool to improve your thinking because it helps you identify and remove obstacles to success. The root of inversion is 'invert,' which means to upend or turn upside down. As a thinking tool, it means approaching a situation from the opposite end of the natural starting point. Most of us tend to think one way about a problem: forward. Inversion allows us to flip the problem around and think backward. Sometimes it’s good to start at the beginning, but it can be more useful to start at the end.”
