The `127 Hours` actor - who is currently studying at several US universities, recently had his own art exhibition, owns a production company and released a book of short stories last month - admits he is so driven to achieve more in his life, he struggles to find hobbies that allow him to completely switch off.
He said: "It`s hard for me to have just hobbies. I`d say I have a couple of hobbies.
"You know, playing ping pong. When I play ping pong, I don`t have the need to go to the Olympics.
"In my life, I do a lot because I have a lot I`m interested in. I don`t know if you can point to one thing or another and say that`s the real me. I am a bit goofy but I love school."
Despite his success as an actor, James insists he is never treated differently by his classmates.
He told Total Film magazine: "They`ve all been great, they don-t treat me differently.
"In the States, the Yale English programme is one of the top in the country so they`re all superstars in their own right."
