Sometimes when you is trying to find out a solution and going through different possibilities someone walks up to you and in 2 or 3 minutes of talk they come up with a workable solution. One way to explain how they did this is that they are not bound by the same rules you are. We get locked up in the rules, the culture, the constraints, the requirements. Genius is figuring out which are the rules that shouldn’t apply and breaking them.
