Three commencement ceremonies this weekend gave Iowa State over 4,000 new alumni. The Graduate college commencement happened Friday, with an address by Susan Lamont, C.F. Curtis Distinguished Professor in agricultural and life sciences. “I propose to you tonight that when you follow your own internal compass guided by your own personal set of wisely chosen and deeply hallowed values, then you will have a life of satisfaction and a life that will make a significant contribution to society and to the world,” Lamont said. “Because I know that 10 years from now it will make a difference that you graduated from Iowa State University.”
