If you work in an office (even part-time, like me) it is worth making the effort to customize your office space so that you enjoy being in it. That's not hard to do if you are a collector like me, with no end of things to fill the space. The trick is not to overcrowd it, as clutter is unproductive. Just pick a few interesting things and group them together.
You can also use your pin board as a decorating space, not just a place to pin telephone messages!
You should also change things around once in a while to keep the space interesting.
