Much of life's success is about convincing others to do what you want them to do.
Whether it's your kids, your dog, your staff, partner or local supermarket, convincing people to do what you want them to do is a key to getting what you want.
For the greater part, this convincing is done on the premise that it's going to be best for everyone if they do what you want. For example: Getting the kids to do what you think is best for them, makes your life better as well as theirs. Or convincing a well meaning telephone call centre operator that a refund would be in their company's best interest will be good for their review and your pocket too.
This rationalisation is necessary for our moral integrity.
