Metadata. Few people bother creating it and no one enjoys doing it, but it's a crucial step if you want to make geospatial data useful to others. Metadata standards are cumbersome, with many fields containing repetitive information. In this video I created for the GIS Practicum course I teach, I show how to create a metadata template in ArcCatalog and apply that template to an existing dataset. Thanks to Keith Pelletier who pointed out that you can safely use the find an replace tools in Microsoft Word 2007 to make changes to your metadata in XML format.
