Many people would be surprised to realize that Chuck Norris is a student of Zen.
He wrote the book, The Secret Power Within: Zen solutions to Real Problems. Here is a short paragraph from the book on gumption and trusting your gut instinct.
The self-confidence to do these things comes from discipline and learning. As you apply these to difficult challenges, you will acquire the personal strength to go on to other successes. There will be times when you don’t know what to do, when your head dictates one course of actions, your gut another. Which to follow? Always go with your gut. If this results in a setback, so what? You can be thwarted, but not defeated. You can be delayed, but not devastated.
