This. I think I/we need have grace on rough days and accept it, while also slowly working to eliminate it. However, one should not focus on the latter, let it come naturally. This is a marathon, not a sprint, and we cannot expect things to get better quickly. Some days I’m able to deliver a perfect lecture on advanced statistical topics. Other days the car dealership hangs up on me because I took to long to finish my first sentence. (Both occurred this week) I just take it in stride and know I am no different than anyone else.
