I'd like to personally learn two new skills/hobbies. Me the writer, not one of my characters. For instance, I've started learning about knapping (making objects out of stones like flint, etc.) because it's an odd thing to learn in the first place, and I find it's easier to write about something if you have a little "hands on" knowledge on the subject matter. The more you read, research and actually do something, the more believable your writing is.
