I enjoy the stories told in this book. Think about pressing pedestrian crossing button to cross streets,sometime you might press several times, why? because no feedback is returned when you press, that causes you to wonder whether your request is taken into account or not. One more thing, when something goes wrong, don't blame yourself immediately,first check it's the problem of the design or not. And want to know how designers think/behave when there is an issue,they don't start to resolve it right away, they rethink again the issue. To you to discover the book then.Hope you enjoy it as well.
