What can we learn from Raghuram Rajan?

It was during his initial days of joining RBI as the Governor. He was being interviewed by press , when one of the reporters asked him a question in Hindi. Now Governor Rajan as a Tamilian having spent most of his life abroad, was not well conversant with Hindi. So, all he could say to the reporter then was that, he could understand the question but was unable to answer it back in Hindi. So, for the moment he would answer it in English but he promised that  he would  learn Hindi soon.
 
The very next day he asked an officer from the Rajbhasha division to teach him Hindi for atleast an hour every week. Well, the rest as they say is history.  Today the Governor gives interviews at length in pure Hindi, except for a word or two in economic jargon which he finds tough to recall at that very moment. 

what can we learn from him ? It's the perpetual zeal to learn something new, no matter what your age is.
