I personally take the route of "One field of expertise, one field where they know what they're doing but not an expert, then one or more minor talents" For my character Colson, for example, his expert skill is Conjury, his skilled but not expert field is carpentry, and his misc talents include first aid and basic cooking. He know's how to wrap a wound and cook 1 or two recipies, but he's not a master doctor or a Bismarck chef.
