If you ask for a favor: Provide a reason.
This increases success rates significantly. If you ask somebody to cut in line, they'll say no. If you add why, it will significantly increase your odds
Use the contrast principle to close deals
You can make the price of an item seem higher or lower depending on the price of a previously presented item.
Reciprocity rule: people like to return favors
People are more willing to do a favor for someone they like. Another person can make somebody feel indebtedness by doing an uninvited favor.
People like to be consistent
We ignore reason and logic because we prefer to be consistent.
Actions reflect true feelings more than words do
Written commitment has great advantages
Set goals and write them down. The goal itself is less important, the more important thing is that you have something to aim.
When many people do a lot of things, it is usually the right
When things are unclear, we look to and follow the actions of others. This is especially powerful among strangers.
We prefer to say yes to people we like
Attractive people are more persuasive by nature.
We don't want to lose things.
We are motivated more by the idea of losing something than we are about gaining something of the same value.
The "deadline" tactic
Place an official deadline on an opportunity. Use scarcity as a weapon to influence people.We hate to lose freedoms we have.
