Aikidoist are people who excel at confrontation management.  Here are four powerful statements that have the ability to change any confrontation. I am sorry.

I was wrong.

I don't know.

I made a mistake.

It doesn't matter who is right and who is wrong.  What matters is one's ability to see the other person's side of the argument.

To be able to say these statements without coercion shows that one has attained a level most never get to.  It shows that one is not only powerful, but humble as well - A combination not easily overcome by an opponent.  The one final supremely powerful statement is "I love you."

Try some of these out next time you are confronted and see just how powerful they are and how powerful they make you.
