He feels no pressure when he screws up and has no problem admitting when he’s wrong and shouldering the blame: When a Cooler makes a mistake, he’ll give you a lot of excuses but no solutions. When a Closer makes a mistake, he finds someone else to blame. When a Cleaner makes a mistake, he can look you in the eye and say, “I fucked up.”
