It’s true that fear can help us from doing stupid things, but sometimes our fear is of something stupid (like the dark). When I was younger I was terrified of the dark, so one day I decided I would face the fear and, hopefully, overcome it. I sat a chair in the middle of my room at night, turned off the lights, and sat there. Not surprisingly: nothing happened. I haven’t been afraid of the dark since. My question to you is this: how do you know when you should face a fear, rather than let it stay a fear? What defines that “stupid” line?
