Julie Tetel Andresen said this quote
“ I remember when I first began writing, I would spend maybe five or six hours on perhaps two paragraphs, and at the end of the day, not only were the paragraphs pretty terrible but I was also exhausted by the effort. I clearly wasn't in shape. You don't just tie on a pair of running shoes and go out and run a marathon. You have to be in running shape, just like you have to be in writing shape. ”
