The 38-year-old actor said he never let money and fame change his thinking process, reported Daily Mirror.
"There is a certain amount of disorientation. You can't relate to having more money than you ever imagined or even know how to spend or invest. It's absolutely luxury, I know that. But I don't think I've let it affect the way I live or change how I think. I still live pretty much like a nomad in going from one film shoot to another.
Cooper's said his father's death in in 2011 was a 'life-changing moment' for him and he owes everything to his father.
