Aamir Khan looks effortlessly comfortable in every character he plays onscreen whether it is the police officer of "Sarfarosh" or the painter in his latest "Dhobi Ghat". But the actor says he still finds it difficult to get into the skin of a character even after two decades in Bollywood.

"I'm yet to find a role (that is) easy, all roles are hard and it's hard to get into the skin of another person.

It's hard to understand the mind of another person because you are very much what you are and when you have to become someone else, it's very important to understand what you are becoming and have an ability to slip into that, " Aamir told.

"So I don't find it that easy, no matter which character I'm playing, " Aamir said.
