The question is how strong is your ego? 

It is your ego that pushes us to be right.

As a matter of fact your ego is more

 interested in being right than

anything else you can imagine. 

Sometimes you can apologize to come to an agreement.  If you understand how your mind works it is easy.  In sales training we come to a agreement with the intent of moving forward.  You can do the same thing with your spouse or partner.  Next time you get into an argument just come to an agreement.  Just let it go. 

Chances are you can not remember what you were disagreeing about.

Move forward, you control your ego!

Have a great day, and a great attitude...
