Will Smith says being an actor has taught him valuable life lessons, especially a diplomatic manner to talk to everyone.
The star believes he has learnt to talk to people even if he hates them, reports showbizspy.com.
"I control every interaction with every human being that I'm with. I've learned that a person isn't just an a**hole, or isn't just crazy. If I am aware I can actually manage any situation with 98 percent of people on the earth," said Smith.
"There are some lunatics but you just can't do nothing with them," he added.
