So far, it's one big pep talk — with many things I disagree with. The author constantly talks about creating for other people, how it's a form of leadership, etc. He quotes a designer who says, "it is not all about you," and that you should create art to "help everyone get along," which they say is important in our capitalist society. Sorry, but I'm not such an idealist that I think my instrumentals are magically going to make someone go, "Wow, sounds great — I think I'll start being nice to people!" And he talks as though this is my DUTY. In fact, he categorically states that art happens when you change someone — "No change, no art," he says. I beg to differ. Most art that I appreciate and enjoy doesn't change who I am.
The whole thing rubs me the wrong way. It's called self-expression, not selfless expression. I create, first and foremost, because *I* enjoy doing so. Is that selfish? Maybe. Is that a bad thing? Of course not.
In short, read this book if you think the goal of your art should be to change the world and other people. If you create for any other reason, skip it — unless you want to start questioning whether you're even an artist. It's a pep talk that will make you feel worse about your art and your purpose for creating it.
