I found this inspiring, especially this:
6. Yes, It Always Feels This Way
You will always have days when you feel like an amateur. When it feels like everybody else is better than you. You will have this nagging suspicion that someone will eventually find you out, call you on your bullshit, realize you’re the literary equivalent of a vagrant painting on the side of a wall with a piece of calcified poop. You will have days when the blank page is like being lost in a blizzard. You will sometimes hate what you wrote today, or yesterday, or ten years ago. Bad days are part of the package. You just have to shut them out, swaddle your head in tinfoil, and keep writing anyway.
