This book is fantastic! The Playbook showed me, in a humorous way, what it takes to succeed in the world of dating for young professionals. It is tough finding quality women, approaching them, asking them out, and dating them after you get your diploma. It feels like the dating pool has dried up and become this big desert. Where did all the hot babes go? The Playbook showed me how to play this new game smart, and save me time that I would have otherwise wasted making rookie mistakes.
