I know that many people do not make them or keep them. I do. If you are a person who at least tries to come up with a list, I've stumbled across a few posted on blogs out there.
Matt Homan has a number of posts regarding resolutions.
A few around my office are simple in idea but may prove difficult in practice: Move to PDF images of all frequently reviewed documents in a client's file. Accident Reports, for example. In a client directory that should be one of the 'must haves' on a server.
I also resolve to use an online medical records acquisition like Mediconnect on a test basis. One attorney in town swears by it.
