I'm a huge fan of Trust Me I'm Lying (It broke the way I see the Internet), and about 20% into this book I'm loving it. The concept of a Perennial Seller that he presents is something every maker should aspire to.
Funnily, going into this I thought the book was more about perennial salesmen - I didn't realise it was focused on product/art creation. Not at all disappointed.
