You’d do whatever you wanted, and say whatever came to your mind if you had achieved Jaden Smith’s success, and that has lead to a terminal case of King-of-the-world-itis, a disorder that he shares with James Cameron and Kanye West. From the time Jaden appeared in “Pursuit of Happyness” to rave reviews, he’s had a pretty charmed acting life. He followed up that film with the blockbuster “The Karate Kid,” for which he received millions. Jaden Smith became a millionaire before he turned 15. Wouldn’t you think you were King of the World? Wouldn’t you say stupid, illogical things just ‘cuz you could?
