It would be great if we got along with everyone and they with us. Or that everyone was our friend. But we are all complex creatures with our own histories and ways of seeing the world. With a commitment to building better relationships with peers and subordinates or even family and friends, issues and problems can be solved or set aside.
One key aspect of relationships and ultimately our communications is to understand our triggers, the words or actions which set us off or push our buttons. When triggered, we are not responding from a rational position. Brain science has shown that in these instances we are in our reptilian brain. So, do you want to be in control in your responses to others or out of control? This is about building better relationships and communications.
