Volume

Keep you voice volume low.  You don’t want to appear as if you are angry or shouting when having a confrontation or dealing with difficult person, so keep it low…. and a little too low is perfectly acceptable.

When your voice is quite low, people actually listen more closely.  Use this to your advantage and be sure that you aren’t yelling, speaking in a louder than normal voice, or even the voice that has the “edge” to it.  Speak very softly.

It works!
