It takes a special attitude to persevere on a U.S. Open setup and no one knows that better than four-time champ Jack Nicklaus: "A difficult golf course eliminates a lot of players. The U.S. Open flag eliminates a lot of players. Some players just weren't meant to win the U.S. Open. Quite often, a lot of them know it." In other words, one way to handle the magnitude of the U.S. Open is to try to forget that it's the U.S. Open.
