We get good at whatever we practice. Choose any one of these exercises to grow your grit by improving your ability to experience and endure discomfort. As you do them, pay attention and notice the thoughts that come up. Why are we doing this? This is stupid. This can wait until later. It’s not worth it. We’re going to die. Become fascinated by your brain’s predisposition to avoid discomfort. That awareness alone will increase your supply of grit.
