Yes Man

Carl Allen's life is going nowhere--the operative word being "no"--until he signs up for a self-help program based on one simple covenant: say yes to everything--and anything. Unleashing the power of "YES" begins to transform Carl's life in amazing and unexpected ways, getting him promoted at work and opening the door to a new romance. But, his willingness to embrace every opportunity might just become too much of a good thing.
