There are a lot of lectures that people have given.

Here I want to make a note of some that I think are essential viewing, or essential reading.

• Richard Hamming: You and Your Research (1986) — also available as a video: Hamming, "You and Your Research" (1995) video
• Randy Pausch Last Lecture: Achieving Your Childhood Dreams video (also available as a book)
