As a professional, you should be continuously reviewing and evaluating your own performance, and weeding the skills and projects that are no longer beneficial to you or your organization. If you realize at any time that you’ve become MUSTIE*, then you should quit your job immediately and allow a newer, better librarian to have your job. If it’s good enough for our materials, it’s good enough for us.
*M is for : Misleading–factually inaccurate. I think we’ve all been there–we’re sitting on the desk with someone else, listening to them give out blatantly WRONG information. Even with gentle correction, our coworker refuses to change his or her way. Or, at best, they decide that they’ll just make you answer all of the hard questions because they’re too lazy to actually do their job.
U is for: Ugly–worn beyond mending or rebinding. Let’s not get into this one too much, except to say that ugly, when it comes to people, applies more to their attitude than their appearance.
S is for: Superceded–by a new edition of by a much better book on the subject. When you use the computer mouse by banging it against the desk, or answer a ready reference question with the phone book, you’ve been superceded.
T is for: Trivial–of no discernible literary or scientific merit. Have you been running the same programs for youth year in and year out with no changes? Do your booklists not have any titles published in the last twenty years on them? Are you chained to your reference desk?
I is for: Irrelevant to the needs and interests of the library’s community. Closely tied with trivial, many of the same questions can be asked. If you’re sitting at your desk waiting for people to come to you with their questions and their needs, you are irrelevant.
E is for: Elsewhere–the material is easily obtainable from another library [or librarian]. There are thousands of people with library degrees frothing at the mouth to work, and at least some of them have to be more outgoing, engaging, exciting, and innovative than your MUSTIE a**. How about you do one brave thing in your professional life and QUIT, so they can have a chance?"
