Mine is The Agent with "DO" Diligence.
At first I thought it was catchy, and now I think it's dorky, so I really don't use it much.
LOL! I was going to suggest:
"I'm a dork and I have a slogan to prove it"
I think slogans make an agent seem less professional. Think about elevating the profession. Do Doctors, or CPA's or Psychologists have slogans? (Lawyers do, but like I said let's try to
elevate the profession.)
