Books for better interaction with clients – asking the questions for: clear answers, discerning what the client really wants vs what they think they want. And managing clients in general as a self-employed person.

I'm considering self-employment as a web developer. I'm good on the technology side, but the art of effectively managing & communicating with people is something I lack.

As someone else put it "the tech is the easy bit", from casual projects with friends I know all too well.

The target demographic is small businesses, so I'm not so worried about high levels of formality and professionalism which might be more critical with something like large enterprise clients, more down-to-earth than that.

It's mostly: asking the right questions, setting boundaries, dealing with problematic clients and such, identifying what the client actually wants, steering the client, and everything else I haven't thought of yet.

I don't need a master class, nor to become a master, but I do need some advice to get better. And yes I need experience, but purposeful experience based on good guidance.

Also, any other related book-suggestions welcome.
