What have you learned from being a client that will make you a better designer/developer?

In class this week, we had to group up with someone and play the role of the designer and the client. It was good for us to be able to look at both side as the client as well as the designer to get a better idea of what is expected from both sides. As the client, as well as the developer I have learned the importance of clear communication. There is nothing worse than a client describing to the designer what the are after and the designer coming back with something that was not at all what they had in mind. As a designer, you dont want to have to do it twice if you dont have to.
