Respect

Respect is a very powerful thing.  You can make or break any relationship by either having and showing respect or the lack of.  A good rule of thumb is to treat everyone as you would expect to be treated.  We all want to be respected so by treating others as we want to be treated........well, you get it.  

Don't expect someone to respect you if you have treated them any less than what you would expect for yourself.  It just doesn't work that way.
