I found the book rather repetitive and felt it provided too little insight into living in space. Many of Chris' anecdotes and their associated lessons were enjoyable, but I never found myself wanting to pick the book up again once set down. It's hard to pinpoint exactly what I didn't like given that each individual story was so interesting and I found it mostly well written. Perhaps it's that what humans have achieved in space is truly inspiring, but unfortunately, this book doesn't reflect that adequately.
