I have just watched this great video of Guy Kawasaki: http://video.google.com/videoplay?docid=-3755718939216161559!!!
It is amazing how many things one can learn in just a 40 minutes presentation of the TEN key points he outlines and evangelizes...
I strongly recommend anyone who wants to start a company to view this video and think again before actually moving on. It's full of truths and things that I have already seen happenning before, and I can tell you (without being a big entrepreneur) that he is right.
I will search for more items like this one, an come back to you, it's really useful and meaningful!
