Quotes

 * When nothing seems to help, I go and look at a stonecutter hammering away at his rock, perhaps a hundred times without as much as a crack showing in it. Yet at the hundred and first blow it will split in two, and I know it was not that blow that did it—but all that had gone before.
 * James Clear's Atomic Habits as attributed to Riis in the San Antonio Spurs locker room
 * Originally from The Making of an American (1901), p. 253
