Dayna English was a highly successful investment banker at Merrill Lynch. She spent most of her career in Latin America. She flew first class, stayed at the Four Seasons when she traveled and wore tailored Chanel suits. But when Dayna turned 50, she traded all that in become a public school teacher. It's been a tough, tough road. But every day for the last ten years she gets on her bike in Manhattan, rides to work seven miles and teach math at some of the most difficult schools in New York City.
