The video is about 1 hour 16min, worth watching,

one of the comment says God bless you Professor Pausch. Though your Last Lecture was meant for your children, it has inspired me in countless ways. I thank you for your insight, wit and sharing. Your family has been blessed having you in their lives. The same may be said for all the students you have touched over the years and those like me who met you through video. Rest in peace,

Randy Pausch Almost all of us have childhood dreams: for example, being an astronaut, or making movies or video games for a living. Sadly, most people don't achieve theirs, and I think that's a shame. I had several specific childhood dreams, and I've actually achieved most of them. More importantly, I have found ways, in particular the creation (with Don Marinelli), of CMU's Entertainment Technology Center (, of helping many young people actually *achieve* their childhood dreams. This talk will discuss how I achieved my childhood dreams (being in zero gravity, designing theme park rides for Disney, and a few others), and will contain realistic advice on how *you* can live your life so that you can make your childhood dreams come true, too.
