Lauren Groff said this quote
“ Even still, we run. We have not reached our average of 57.92 years without knowing that you run through it, and it hurts and you run through it some more, and if it hurts worse, you run through it even more, and when you finish, you will have broken through. In the end, when you are done, and stretching, and your heartbeat slows, and your sweat dries, if you've run through the hard part, you will remember no pain. ”
