I've read the book, as well as Influence. Influence is a far stronger book because it does a better job of describing the theoretical underpinnings of why the 50 tricks work.

Some of the tricks are really narrow and so they aren't all that useful themselves (e.g. to write post it notes and put those on interoffice forms and surveys for a better response), but with the theories you can make better extrapolations.

With the one about towels (number 2), I wonder if people behaved better because they thought they were being monitored; and, if so, whether some of them decided not to stay in that hotel again.

I wonder how to best apply this to job-seeking.. Hmm...

I guess the original suggestion corresponds to the "experience" section on your CV/resume; it's demonstrating that others have hired you.

Yeah, that doesn't really work for someone just coming out of college next year, with no experience, unfortunately.
