The speech of Seth Godin about "permission marketing" at Google was one of the first speeches I wanted to include here when I started Spoken Gems. Even if you’re not interested in marketing it is fun to watch.
I also recommend Seth Gondin’s blog. It might seem a little bit odd at first but once you get used to it, it’s amazing how many great articles you can find there.
Guy Kawasaki talks about why entrepreneurs need mantras instead of mission statements and why they should ask women about their business model. This one is a must-see for all people thinking about starting a business.
