Okay, I'm going to ruin the book for you. Ready?
Danny Wallace wrote humorous non-fiction books before this one. There's a small hint of it while he tells the story, but if you look here on Amazon, you'll find
Join Me! and a few others.
"Yes Man" is still great. It's a very fast read and the anecdotes from Danny's life over six months (it's not a year) are all well-written. You would think these mini-stories would just be amusing stand-alone chapters, but Danny does a great job of putting them together in an overall narrative showing growth and understanding.
He forces things a little when talking about his transactions with online spammers, and his interactions with drugs are out of a stereotypical movie (now starring Jim Carrey, ha!).
"Yes Man" still ends up being strong, though, because the overall message is reinforced through humor - you should say "yes" to open yourself up to possibilities in both personal and work matters. Danny Wallace does this, and it's a great ride.
Read it, and definitely share it with others who seem to be stuck in a rut.
