You can even develop a unique selling proposition out of a personal quirk
. There was a lawyer in my area once who loved the color red. Everything related to his lawyer advertising was done in some shade of red - logos, pens, business cards. He even went as far as to have a huge red sign outside his building. Do I remember his name? No, but I do remember he was the "lawyer who really loved red" and I can still tell you where his office was located.
