Daniel Pink description of how to persuade someone could be seen in the lightofempathy.
He refers to Mike Pentalon of Yale University on Motivational Interviewing.
If you want to persuade someone, ask two irrational questions:
1: On a scale of 1-10, one meaning I am not ready at all, ten meaning I am ready. How ready are you, ___(Maria) to ______ (clean your room)?
2: Okay, you say you are a_____ (two). Why didn't you pick a lower number?
Now, the other person has to explain why he/she isn't a one and begins to articulate his or her own reasons for doing the thing. (Not reasons for not doing it, but reasons why he/she would do it, because person values herself better then the lower number.)
If answer is a "one": say: "What can we do to make you a two?" - A one is because there is an environmental obstacle in front of them that you can help to take away.
"Motivator's role is to service people's own reasons for doing something"
