AOL CEO Tim Armstrong has taken a series of smart risks throughout his career that have helped him reach the top. He began as a college student in Boston who managed a strawberry farm. He later became a hotshot Internet advertising salesman who sold the first-ever $1 million campaign online. He impressed Google's cofounders in an early job interview, and helped build their advertising business from scratch. Now he is the CEO of AOL, and he has lots of advice for others who want to run corporate America some day.
