How we talk, listen and act around other people is the bread and butter of our connection with them. What kind of a relationship and how we communicate with ourselves will be faithfully reflected with what kind of relationship and how we communicate with other people.
Talking, listening and cross-check -- making certain that you're on the same page -- is as important to our relationship with ourselves as it is with our relationship with others.
Life is an "inside/outside"’ phenomenon. How we are with ourselves will be faithfully mirrored with how we are with other people. It's all a matter of balance.
