I was cruising round Paul Jacobson's blog, one thing led to another and I ended up at Matt Homann's blog. I think his blog on 15 Rules for Clients: A Mini Manifesto is absolutely brilliant. I'll start you off on the first two, but after that you'll have to follow the link.
And after that, take a moment to read the sequel 15 Lawyer Tips: A Mini Manifesto by way of ripost. This time I'll start you with 3 and 4.1. You have wants. You have needs. Focus on the needs first. Wants are bonus.
2. If you are seeing a lawyer because your dispute is "not about the money, but about the principle of the thing" don't be surprised if your lawyer runs away. You can never be satisfied. Also, it's really about the money.
I think a fair chunk of the points apply to more than just lawyers.3. Every time your clients get your bill, they think about how beautiful your office is and about the nice car you drive. And they wonder if you are worth it.
4. If your office is a dump and you drive a wreck, they wonder about that too.
