Prakash Rao works 12 hours a day as a chai waller (tea beverage vendor) and donates half of his earnings to help poor kids get an education.
Watch the short documentary Brewing Minds to see why helping a slum school in the Indian city of Cuttack makes 58-year-old Rao the happiest man on earth. On top of that he has donated blood to the local hospital over 200 times.
He should be an inspiration to us all.
