The main reason this books isn't getting a higher score is that I'm not into "Big Idea" books that don't give practical advice which is essentially what this book is - it is very low on advice and stuff to-do.
Seth rails on about being an artist where "Art" is pretty much anything you are passionate about. The book is about going for it, daring to be different and the usual melarchy that you find in a self-help motivational books.
If you're lacking in inspiration or feeling like you might need a little preaching to make you "go for it" then you may well find this book useful. As for me, it was good enough to finish but I would not have lost anything by never having read it.
Time allowing, I love to read. If I read anything interesting, I will blog about it here.
