The 32-year-old 'Mirrors' hitmaker thinks he has taken risks in his career which has been rewarding, reported People magazine.
"Listen, I'm not cool. Being cool is about keeping your blood pressure steady. So no. Don't be cool. Be passionate. Be dedicated. Be tenacious. Be uncompromising. Be pissed. Be happy. Be sad," Timberlake said.
"I've made a career out of doing things that I should not be doing. I wasn't cool about it," he added.
