"An individual will start to treat himself like others have treated him! And you can put that down as a law. He'll treat himself as others have treated him. And he will also treat others as he treats himself. Works both ways." - L. Ron Hubbard
I can think of many times I've acted how others said or expected I'd act - even if I didn't really want to. I've then treated others in the same way. It's pretty interesting how this vicious circle occurs - you treat someone poorly, they treat another poorly, etc.
Have you ever encountered this?
