People do things for their own reasons.
One of the most effective ways to approach the task of persuading another person is to realize that they simply do not care a bit about what YOU want.
They only care about what THEY want.
If you want someone to do something, then you must show them how doing it will give them more of what they want.
And if you don’t know what they want, take a few minutes and ask them. Most folks are all too eager for someone to listen to them, and will happily reveal the “hot buttons” you can push to get what you want from them.
Affirm: I can get what I want by helping others get what they want.
