Seth Godin's lizard brain video

Merlin Mann of 43 Folders interviewed Seth Godin about his book Linchpin - and mentioned a presentation that Seth Godin had done - See link above. Godin says don't let your lizard brain stop you: You must ship. Just get the work shipped. How did I get to this from what I've been reading, etc? I went to another interview with Seth Godin with Steve Hargadon. See http://tr.im/futureofed - May 5, 2010 event.
