Whatever anyone does, whatever anyone says, is aligned with how they see the world.

And so decisions people make are always perfect for them in the sense that all their education, learning, experiences and insights into the world lead them to that decision.

So when dealing with other people, it's important to understand that whatever they are doing makes perfect sense with how they see the world.

So start by understanding what's there for them, and deal with that.

There are no mistakes.  Everything is perfect.
