The actor will be seen next in the superhero franchise movie Krrish 3.
He told The Times of India: "I don't look back, what has happened is done. It is not my time to look back just yet, probably when I am too old in the industry I will do that.
"But right now I just want to look forward and concentrate on good work. 2013 has a lot of good work in store for me. I don't have time to look back."
Oberoi added: "I play this super villain in Krrish 3 and it is a very dark and intense character. I have never done anything like this before. In fact, on the first day of the sets, Hrithik [Roshan, co-star] told me that he wanted to do this role initially so it was a huge compliment. I think I am very lucky to get that part."
The actor recently said marrying his girlfriend Priyanka Alva has changed his attitude towards life.
Last year he admitted that the failure of the drama Rakhta Charita had been the "low point" of his career.
