Over on Career Hub, Billie Sucher wrote about what constitutes a good client for her. That got me thinking about the same question for me (answered below), and about you. Who is a great client for you? I'm not talking traditional market segmentation here. Rather, the question is, "What client behaviors do you love, and which do you hate?" Read my list, check out Billie's list, and then figure out your list. Please share your list in the comments section, if you like.
