In response to my spiralling self-doubt, I discovered many a strategy to cope with it. One method is to write a letter, personifying your internal enemy.
Here’s an example from author Elizabeth Gilbert. In her book Big Magic, she wrote a letter to Fear:
“Dearest Fear: Creativity and I are about to go on a road trip. I understand you’ll be joining us, because you always do. I acknowledge that you believe you have an important job to do. But I will also be doing my job, which is to work hard and stay focused. And Creativity will be doing its job, which is to remain stimulating and inspiring. There’s plenty of room in this vehicle for all of us, but understand this: Creativity and I are the only ones who will be making any decisions along the way. You’re not allowed to suggest detours. You’re not allowed to fiddle with the temperature. Dude, you’re not even allowed to touch the radio. But above all else, you are absolutely forbidden to drive.”
Feeling inspired, I wrote my own letter to Doubt. I must admit, it might not be quite as eloquent:
Dear Doubt: F*** you.
