Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Extremly basic

This tiny little book should have the word "Lite" in the title and should have a lower price than it does. Although there are some solid basic ideas here, MUCH is left unsaid. It doesn't pack any real punch and one could easily recognize this, even if you didn't have "a very low IQ" (as another reviewer suggested anyone who didn't like it must have). Check out books on selling with integrity and you will find exactly what you're looking for.
