Man on Wire

I recently saw a documentary made in 2008 about the man who tightrope walked between the tops of the twin towers in 1974. Philippe Petit and a small group of friends snuck themselves, and over 500 lbs of equipment to the top of either tower of the world trade center. They rigged up a tightrope overnight and, at 7:15 in the morning "The 25-year-old Petit made eight crossings between the mostly-finished towers, a quarter mile above the sidewalks of Manhattan, in an event that lasted about 45 minutes. During that time, in addition to walking, he sat on the wire, gave knee salute and, while lying on the wire, dialogued with a gull circling above his head."
Here's the trailer for the documentary:

This is the single most motivating thing I've ever seen in my life. I recommend that every one of you watch it.
