Just a few years ago, Adam Braun looked down the road to a rich life, in the monetary sense.
He'd been working at hedge funds since he was 16, and a Wall Street career seemed pre-ordained.
Then Adam traveled through India, and met a boy who wanted a pencil. Just a pencil.
Now Adam Braun is the head of the non-profit Pencils for Promise and the author of a book about its school-building activities, The Promise of a Pencil.
