It's a great "cheat sheet" because he gives pointers on how to find out whether the girl is sexually attracted, sexually available, and whether the "logistics" are good or not. In short, follow those pointers and get laid, or ignore them and keep wasting time with girls that aren't interested. If you still carry around a cheat sheet with routines, then it's probably time to replace it.
To whet your appetite:
To have sex you need to:
- find out if she's sexually attracted to you
- find out if she's sexually available for you
- have good logistics
