“You can’t get much done in life if you only work on the days when you feel good” is a saying that has been printed on posters. The saying has been attributed to basketball star Jerry West since at least 1997, but it’s not certain when he said it.
 
   
Wikipedia: Jerry West
Jerry Alan West (born May 28, 1938) is a retired American basketball player who played his entire professional career for the Los Angeles Lakers of the National Basketball Association (NBA). His nicknames include “Mr. Clutch,” for his ability to make a big play in a clutch situation, such as his famous buzzer-beating 60-foot shot that tied Game 3 of the 1970 NBA Finals against the New York Knicks; “The Logo,” in reference to his silhouette being incorporated into the NBA logo; and “Zeke from Cabin Creek,” after the creek near his birthplace of Chelyan, West Virginia. Playing the small forward position early in his career, West was a standout at East Bank High School and at West Virginia University, leading the WVU Mountaineers to the 1959 NCAA championship game, earning the NCAA Final Four Most Outstanding Player honor despite the loss. He then embarked on a 14-year career with the Los Angeles Lakers, and was the co-captain of the 1960 U.S. Olympic gold medal team in Rome, a squad that would be inducted as a unit into the Naismith Memorial Basketball Hall of Fame in 2010.

Usually, he suffers from “source amnesia” when he spouts his stuff, that memory lag in which you can remember a statement without recalling where you heard it, or whether the source was even credible.
 
So the giant quote Lawrence Frank had painted across the locker room wall this preseason has no credit line under it: “You can’t get much done in life,” it reads, “if you only work on the days when you feel good.”
 
Sounds familiar.
 
“Actually, that one is Jerry West,” Frank explained. “They just forgot to inscribe it. I got another one: ‘If what you did yesterday looks great, you didn’t do much today.’”
