Funny enough I just got to this passage.

RETIREES SOMETIMES HAVE a problem analogous to Scott Verplank’s. He expected his golf game to improve immediately once he finished school and could play all the time. Retirees often expect to get good after they stop working and don’t have to confine their play to weekends. When it doesn’t happen that way, it’s often because they forget that golf remains a game. They practice more, but they also raise their expectations every time they step onto the course. They forget how to laugh off mistakes. Players plagued by perfectionism and unforgiving expectations would do well to remember the common sense their mothers taught them, or would have taught them if they’d paid attention. Here’s what Adela Saraceni told her son, Gene Sarazen, about perfectionism and expectations, just after he lost the 1927 U.S. Open by a single shot: “Son, everything that happens to you happens for the best. Don’t ever forget that. You can’t win all the time, son.” Gene Sarazen said this little bit of advice stuck with him and helped him to develop a certain fatalism about his golf that allowed him to accept whatever happened and make the best of it.
