A very short one, made of collections of interviews and essays. I finished it within an hour and that's also how I felt afterwards. While there is quite a bit of nice and inspiring information in there, I kind of missed the motivating words in the end, that just make you want to jump up and start crafting.
Still, a nice little quicky if you are into product creation.
