A few excerpts from his video:
A viewer of one of the videos Salman created, a viewer said
“First time I smiled doing a derivative.”
Then in response to the above, another commenter said
“Same thing here, I actually got a natural high in a good mood the entire day.”
Khan says that a parent with an autistic child wrote him to thank him. A video on decimals got through to this child and the parents are thrilled. The child moved on to fractions.
He says that he was an analyst at a Hedge Fund and when he first started doing something of social value , he felt strange. 
It is a great presentation.
