a copy of RAZ?

You say this as if it's supposed to score style points with people. Most would probably think you're a paid salesman for the authors. If you value the advice within this much, maybe you should just read it until you're familiar with most main points, rather than carry it around.

Edit: Also, people are pants at borrowing other people's standards for interpersonal evaluation. Seeing yourself on a camera improves things, but only somewhat; if you have a socially unacceptable aspect of yourself that's at the same time ego-syntonic, then by the gods that aspect is going to stay with you and hinder you.
