The Sandy Weill story is truly one for the ages. Starting with $30,000 in borrowed cash in 1960, and relying on uncanny entrepreneurial instincts in the corporate world, he made himself a billionaire and became one of the most powerful bankers in the world. After rising to become the president of American Express, Weill saw his empire crash and burn. Undaunted, he started over with a second-tier consumer loan company called Commercial Credit, which eventually led to his position as CEO and then chairman of Citigroup. While at Citigroup, Weill delivered an astounding 2,600% return to investors, better than legendary CEO Jack Welch or investor Warren Buffett during that same period. But success is never an easy path, and Weill shares all the high and low points along the way.
