This book has influenced me the most, personally in shaping my mindset and also in all my intrapreneurship and entrepreneurship related initiatives
This is the perfect book for anyone trying to create a new product or service. As you know, Peter is one of the co-founders of PayPal and this book is basically the notes of his Stanford lecture.
The CEO of Vooza gave this funny key note at a conference recently, it really cracked me up.. If you haven't heard of Vooza before, they make funny videos on tech companies, check out their website http://www.youtube.com/watch?v=ry4d2HQqXfA
