The Power Guys Under 30

Justin Timberlake, T.I. and Usher made Stuff magazine’s “30 Power Guys Under 30” list, which also includes actors Seth Rogen and Jake Gyllenhaal; athletes LeBron James, Reggie Bush, Tom Brady, Roger Federer, and also blogger Perez Hilton. T.I. shares his secret to staying on top in the magazine’s August issue, which hits newsstands Tuesday.

“You must create a demand and then supply it,” he explained. “You make so the market can’t function at its best without you.”
