I am a huge Lou Holtz fan. His motivational speeches are awesome. He has a passion for life that is infectious and is a wonderful example on leadership.
David Stollman from CAMPUSPEAK is a fantastic speaker. We recently spoke, and I could remember parts of his presentation from the only time I heard him speak – 10 years ago! If you ever get a chance to hear one of his presentations – you need to take advantage of that opportunity.
