What are some inspiring videos I can watch to renew my passion for startups?

I remember when I was learning guitar and it was so frustrating in the beginning, I used to watch great rock guitarists and draw inspiration from them. Videos of live performance kept me going. Extending the same analogy, is there some great startup videos that I can watch to get inspired when I am down and demotivated?

I highly recommend Derek Sivers' videos: http://www.youtube.com/dereksivers

Inspiration can be highly personal. This is the video that did it for me. "When you want to succeed as bad as you want to breath, then you'll be successful."

By now there's a pretty good collection of talks from Startup Bootcamp at MIT: http://www.youtube.com/startupbootcamp

Some notable speakers:

    - Drew Houston (Dropbox) both in '09 and '11
    - Patrick Collison (Stripe)
    - Alex Polvi (Cloudkick)
    - Leah Culver (Convore)
    - Chris Wanstrath (Github)
    - Bill Clerico (WePay)
    - James Lindenbaum (Heroku)
    - Kyle Vogt (Justin.TV)
    - Adam Smith (Xobni)
    - Angus Davis (TellMe)
    - Paul English (Kayak)
    - Alexis Ohanian (Reddit/YC)
    - Dan Bricklin (VisiCalc)
    - Stephen Wolfram (Wolfram Research/Alpha)
    - Bob Metcalfe (PARC, 3M)

This is just for fun (not informational at all), but I love how it parodies the startup culture.
