I find that this quote is not just applicable to writing of natural language like letters. It also applies to code, and is becoming more and more evident to me due to the use of AI. I believe the idea presented transcends writing actually. For example you could also apply it to painting or sculpting. I think this points to the character of creative thinking where one "chips" away at a subject until it is considered as finished.
