Now that we are talking entrepreneurship and now that "Løvens Hule" (Dragons' Den/Shark Tank) is running, I have have to recommend this book - one of the best business books which I have ever read - 'Zero to one' by Peter Thiel, who among many things was angel and the first external investor in Facebook and co-founder of PayPal and much more. It is a deeply interesting and relevant book on entrepreneurship, but also about the faces of capitalism, the future and about what creates success in the 21st century. Give it a chance- it's not as heavy as I probably present it; not even 200 pages long and very well written and accurate.
