Carl Allen signs up for a self-help program based on one simple principle: say yes to everything ... and anything. Unleashing the power of 'yes' transforms Carl's life in amazing and unexpected ways, but he soon discovers that embracing every opportunity might just become too much of a good thing.

Yes Man is a memoir written by Danny Wallace based upon a year of the author's life, in which he chose to say "Yes" to any offers that came his way. It was also loosely adapted into the 2008 film Yes Man starring Jim Carrey.
