They have not been from clients (perhaps potential) they have been from random people. I believe that we all have to start somewhere, and it only takes one "random" person to read a blog and pass the word along to another before the ball starts rolling.
I am not exactly sure who the people are or where they are in the business world. I should probably check that out!
I too feel like I am talking to myself half the time, and for the most part I probably am...I guess I just keep holding on to the thought "If I keep talking, eventually SOMEBODY will listen."
SHOOT FOR THE MOON AND LAND IN THE STARS!!
