I’m reading the most recent marketing Rebel Rant by John Carlton. You won’t find it online – You have to pay plenty for this information.
The theme is the difference between introverts and extroverts and knowing how to market to each type.
…that understanding human nature means going deep into the head of other people, and allowing for the fact they may process information and experience life in a radically different way than you.
Specific advice:
The rookie won’t realize that many people will not call a toll-free number simply because they don’t want to talk to anyone… but they WILL call a recorded message.
Sorry, can’t give everything away 😉
