give and you shall receive

Learned something interesting today. If you start off a phonecall with a question to engage your audience, you are twice as likely to make a sale. If you give someone something, they are twice as likely to reciprocate when you ask for something in return. If I can somehow combine these two techniques, I will quadrouple my chance of convincing people to do things they wouldnt normally do. Now I just need to go read The Art of Deception...and figure out what I want to get...:P
