Don't let your cases stagnate. It's an obvious rule, yet one that's broken more often than plaintiffs' lawyers like to admit. Here's a simple technique that will force you to keep moving ahead on many fronts at once: keep a list of all your cases, and make sure that you spend time on them each week. Try to always keep the defendants on the defensive--with discovery requests, depositions, or any other type of case preparation--and when they bat the ball to you, bat it right back.
What about those files that you have developed a personal aversion to working on because you're having problems with the client or because you've lost interest? First, try to snap out of it. You owe it to the client and to yourself. But if you can't, it might be better to withdraw, rules permitting, than to let the problem grow worse with each passing day. Why complicate a bad situation with a malpractice suit?
