The richest man in the world can now also claim a degree from the college he dropped out of three decades ago.

Microsoft Chairman Bill Gates delivered the commencement address at Harvard University here Thursday, and was awarded the L.L.D. honorary doctorate bestowed upon Harvard's commencement speakers.

"Our speaker is known as the most influential entrepreneur of the personal computer revolution. He was named as one of the 100 most influential people in the world in 2004, 2005, 2006 and again in 2007," said Harvard's interim president, Derek Bok, who presided over the ceremony. Bok then spoke more directly to Gates: "Just think what you could have achieved if you had stayed another two years."

Even though the school has said that it considers him to be a member of the Harvard College Class of 1977, Gates dropped out of Harvard as a junior in 1975 to run Microsoft full time and never got his bachelor's degree.

Gates told the students, many of whom will soon be launching into full-time careers, that work isn't the only thing of significance.

"Judge yourself not on the professional accomplishments but on how well you have addressed the world's inequities, how you have treated people who have nothing to do with you other than a shared humanity," he said.

"...how you have treated people who have nothing to do with you other than a shared humanity..."

What? Can someone tell me what he has done for people "who have nothing to do with you other than a shared humanity?"
