Those have to come from you. Don't let the term "guerrilla" fool you; it is not as cool or revolutionary as it sounds; it's just a name for an effective small businessman. I definitely plan on picking it up again, someday, when I finally start a business of my own! Also covers a lot of obsolete or redundant information but I guess that's too be expected even if it has supposedly been updated since The importance of body language is, but not anything about how to read or use body language.
