One of the most important lessons I’ve learned is that frustration is a part of the process. I’ve rarely written anything good that did not come out of moments of extreme frustration. It’s the frustration that propels you forward. If it doesn’t — if you back away from it — the work will be less than it could have been. When I teach writing, I find that students are relieved to hear this... that frustration is an indication of a literary problem to be solved, not a sign that they aren’t good enough writers.
