3 Idiots and Chak De India

I'm a strong believer that who we are shapes a lot of our decisions. So assuming that hypothesis is true, let's try to look at two roles from two major bollywood actors: Aamir Khan and Shahrukh Khan. The purpose to try to see how how they perceive themselves - or project themselves if you will - based on what appeals to them in a role.
The two roles we'll look at are - Shahrukh as Kabir Khan in Chak De India and Aamir Khan as Ranchoddas (Rancho) in 3 idiots.

Take Racho's character, A genius , who believes the right way is to chase excellence and not success (box office?) which will chase after you if you excel at what you do. The traditional system doesn't understand him and resists his ways at first but ultimately he proves his mettle. Interesting to note that Aamir's characters doesn't do badly in the courses but tops it - despite doing things against the system, and eventually is very 'successful'. If you remove the context of the movie from the above interpretation you could almost be talking about Aamir Khan the actor - or at least a way he's quite likely to see himself.

Now take Kabir Khan's character played by Shahrukh - he's a talented, loyal, hardworking who has been wronged by circumstances and people. He has everything going against him - except his faith and confidence in himself. Even at his lowest, despite no one else believing in him, in his heart he knows he can pull off a miracle and he goes ahead and does that, reinventing himself. Again, remove the context of the movie and it's a character that you can see would appeal to Shahrukh - the outsider who on the basis of his talent, against all odds fights to pull off a miracle and becomes a loved, appreciated star.

Any other interpretations? Thoughts?
