today Andy Seidel, CEO of a water company, came to class to talk to us. Who would have thought he could be so interesting? i mean, he spent the past decade and more selling water processes and systems? hm.
Well, he exhibited a fine art of engaging people. I was suitably impressed.

"take a look around you. this is the last time you are going to be surrounded by so many smart people in a classroom."

Prof Flavio had a pretty good quip today too.

"Look at this slide. Remember this slide for life. I would want you to print it out and fold it and keep it in your wallet. On your wedding night, take it out and have a look at it when you have any doubts. Well, not that it is going to help anyway."
