I have to thank you for your "Ph.D. Grind" memoir. There were many lessons in it, but the lesson I took from it, as I recall from reading it several years ago, was basically that you have to discard perfectionism to get anything done.

I'm not sure if that was even an intended message, but that's what I took from it, and I thought back to it during the dark hours of dissertation writing when I was repeatedly thinking "this isn't good enough". I also remembered the lesson that one should be willing to be flexible in the sense that the dissertation doesn't have to be exactly (or at all) what you originally intended it to be.
