At the May 2 University of Michigan commencement, Google co-founder Larry Page encouraged graduates to dream big.

"I think it is often easier to make progress on mega-ambitious dreams. I know that sounds completely nuts. But, since no one else is crazy enough to do it, you have little competition. There are so few people this crazy that I feel like I know them all by first name. They all travel as if they are pack dogs and stick to each other like glue. The best people want to work the big challenges.''
