Where high-test coffee fails, sometimes an inspirational movie speech succeeds in rousing the central nervous system. Here's one that works for me. (Hat tip: Dennis Cozzalio.)
Which movie speeches work for you? I'm fond of Reese Witherspoon's valedictorian speech at the end of Legally Blonde and Jimmy Stewart's filibuster in Mr. Smith Goes to Washington, but those are longish. Can you think of shortish ones. And can you place the score accompanying this clip? I'm guessing it's from Independence Day.
