I'm guessing not a week passes that you don't need to persuade someone to do something or change something.
Just this week, my persuasive communication included asking for an extension of a gift card expiration date, requesting reimbursement of a client travel expense previously denied, getting an appointment changed to a more reasonable time, and negotiating a new arrangement with a supplier.
So when needing to work out a mutually rewarding deal--or simply change someone's mind on a social or personal issue--I try to keep some of these favorite comments in mind:
