Buying or selling a home is a deeply personal decision for most people. There are tons of different reasons for purchasing or selling, from a first home, needing a larger home, downsizing, schools, different neighborhood or style of home. Whatever the underlying reason it will always be unique to that buyer or seller.
A real estate purchase or sale is inherently tied to individual needs, goals, desires and circumstances. Therefore, it should follow that their real estate agent takes the time to listen, learn and strive to understand each client's personal situation, their fears and concerns as well as the short and long term goals.
Clients don't care how many other people their agent is working for right now, they want to feel like they're the agent's ONLY client.
They want to know that their agent will be there when they need them. That they not only have support, but that their agent will take the time to listen to where they're coming from, where they're trying to go and what they fear along the way.
That their agent will be there to support them throughout the life-changing process of buying or selling a home, not just at the offer or closing stage but through the entire process. They don't want to feel like just a number (client 38426 doesn't have a very warm or personal ring to it), they want to feel like a real person who has a real agent.
You don't have to agree with me, but I truly believe support, service, responsiveness and partnership with clients are critical elements of the real estate relationships we as agents have with our buyers and sellers. The "business" of real estate is (in my opinion) very personal in nature.

All the qualities you described is EXACTLY what every agent should be- I completely agree!
I think that if clients ask how many people you work with, or homes you've sold, shows an underlying concern that you are able to take care of them and their needs. You need to assure them that you are able and will take care of them through their purchase or sale.
