I'll list a number of tasks here. Maybe it's a lot of tasks. Maybe it's too many, and I'm looney-tunes for doing all of these things every six months. But you don't have to do all of them in one day, or even one week. I'm not even putting them all in one post. And it's most onerous the first time you do it: the work you put in now pays off in time and in your budget later on. Here goes!
