I suppose the concept of inspiring people through great oration is particularly appealing to me and when I am in need of inspiration I turn to reading or listening to amazing speeches.
A recent favorite of mine was Steve Jobs’ amazing commencement speech to the graduating Stanford class (http://news-service.stanford.edu/news/2005/june15/jobs-061505). I also turn to this amazing site: http://www.americanrhetoric.com/. Most of the speeches don’t speak to me the same way Steve Jobs’ speech did, but are still extraordinary in their own way.
On a related note, my favorite collection is a 4-disk series called Great Speeches of the 20th Century (http://www.amazon.com/exec/obidos/tg/detail/-/B0000032HG/qid=1131305321/sr=2-1/ref=pd_bbs_b_2_1/002-2587874-9276850?v=glance&s=music). I listen to them every year and think most of you would really enjoy it too.
