Justin Timberlake is his own toughest critic. The multiplatinum-selling singer admits he finds watching or listening to his own work “painful.” (Finally we agree on something.)

“It’s painful for me to either watch or listen to myself,” Justin says. “But even when you’re not fully satisfied with the outcome, that’s what makes you hungry…There is gratification in the fact that you a. make people smile, b. make people dance, c. make people laugh or d. make people make babies.”
