People support a world they helped create.
The only way on Earth to influence other people is to talk about what they want and show them how to get it.

If you disagree with them you may be tempted to interrupt. But don't. It is dangerous. They won't pay attention to you while they still have a lot of ideas of their own crying for expression. So listen patiently and with an open mind.
To be interesting, be interested.
Talk to someone about themselves and they'll listen for hours.
