Before you give today's final presentation, read this.

This is an excerpt from the University of Michigan commencement speech given by Larry Page, one of the founders of
Google.  For the whole speech, click on the title of the post.

"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. That is what
happened with Google. Our mission is to organize the world's
information and make it universally accessible and useful. How can
that not get you excited? But we almost didn't start Google because
my co-founder Sergey and I were too worried about dropping out of our
Ph.D. program. You are probably on the right track if you feel like a
sidewalk worm during a rainstorm! That is about how we felt after we
maxed out three credit cards buying hard disks off the back of a
truck. That was the first hardware for Google. Parents and friends:
more credit cards always help. What is the one sentence summary of
how you change the world? Always work hard on something uncomfortably
exciting!"
