Hey there. Orianna here from Fortune.

NBA champion Metta World Peace (previously known as Ron Artest) has a warning for anyone who thinks they’re a hard worker: There’s probably someone—maybe even on your team—willing to work even harder than you. It’s a career lesson he learned from Kobe Bryant.

In an on-stage interview with me at Web Summit Qatar, World Peace revealed that he had heard the late Los Angeles Lakers basketball player was grinding hard at the gym before long days of grueling training.

So one day, World Peace showed up to the gym at 8 a.m. to see if the rumors were true. “I got to the gym, and I said, ‘Let me see if Kobe is really in the gym.’”

He arrived at 8 a.m.—what he considered early—and Bryant wasn’t mid-set or cooling down. He was already leaving.

“He was all showered up. He was done,” the 46-year-old recalled. “And I thought I was working hard!”

The next day, he went back at 5:30 a.m. to catch a firsthand glimpse of just how far Bryant was willing to go to be one of basketball’s greatest players, including five NBA championships, 18 All-Star selections, and the 2008 MVP award, which he received the year before World Peace joined the team.

The takeaway? High performance is relative. No matter how early you start or how many hours you put in, someone else will be willing to do more.

Or as World Peace put it: “There’s always somebody out there working harder.”
