This is a no brainer for me. I would spend my Thanksgiving with some of the greatest minds ever. Benjamin Franklin and Thomas Edison. They changed the world in immeasurable ways in their lifetimes. I would love to talk to them, find out what made them tick, and how their minds worked. There would be no way to duplicate that greatness but I'm sure that some of it would have rubbed off on me. The other person I would have at the table is Ralph Waldo Emerson. He was such an insightful man and I would love to pick his brain too.
There are so many more people but I would have to write volumes to list them all and why I want to meet them. It would take a large convention center to hold them all and miles of tables to seat them all. I strive to learn as much as I can from as many people as possible. The ones I listed are just the tip of a very big iceberg of knowledge and inspiration.
