Rock Brain will try to make sure that you make only bad choices so a problem only gets worse, or he will get you to try one solution that's not working over and over again.
He will make you get stuck on rules and get stuck on ways that you want to do things without thinking about others.
Some ways that Superflex suggests taking on Rock Brain:
Notice that what you are doing is not working and try another way to solve the same problem.
Remember that being part of a group means that you cannot always do it your way or have everything that you want.
Use self-talk: "Not a problem. I will get to do this later or maybe another time."
Try to think about others' plans and adjust your thinking to match their plans.

Four Steps to Flexible Thinking
Take a deep breath.
Realize there are things you can't control.
Change your plan (What do you want to do? How do you want to do it? How do you want to do it if your first plan doesn't work?)
