Should Your Clients Be Committed?

I had an interesting discussion last week with a marketing professional. We were trying to figure out how we can work together and I asked her "how could I help you."  She said that she was "looking for committed clients". I thought that this was one of the coolest and most powerful things I had heard in a long time. Think of what it implies... 1) She only wants to work with clients that will really appreciate her work and be engaged and, 2) She has enough work that she can pick and choose who she wants to work with. With respect to #2, I don't know if it is true. Maybe she has plenty of business, maybe she doesn't. Clearly, she is open to more business. But that statement implies a lot of confidence, and confidence sells.
