If we have an interaction with someone, we’re often looking for something to gain ourselves. This is logical, but it is easy to get stuck this way: others just aren’t interested in something you want. The basic idea is that people want to do things that benefit themselves.

This often triggers a radical shift in your message and can have a huge impact.
