Michael Bloomberg started his New York City story sweating in his underwear in Salomon Brothers' vaults.
And in a little over 20 years he turned a $10 million severance package from that now defunct bank into a multi-billion dollar company Wall Street can't live without.
The inspiring journey, with plenty of highs and lows, is one of a man who enjoys both success and philanthropy.
His current gig is only paying him $1 per year, but it's not like he needs the money. According to Forbes, he's now the 11th richest man in the world.
