This week we begin graduation season. Many of the college going young adults in this country will end their educational journeys, or will begin the next chapter. All throughout the country, colleges and universities will attempt to impart their graduating classes with great wisdom from many leaders in many fields. Today, for our Learn from the Leaders segment, I would like to present three of those commencement addresses. Today we'll hear from Apple CEO Tim Cook, former President George W. Bush, and legendary partyer and musician Jimmy Buffett.
