I work from a home office (and from my car). To be honest, I find that the only way to stay productive is to stop reading all the blogs & websites about how to stay organized and be productive. Instead, I just STAY PRODUCTIVE and ORGANIZED. And, I just DO the stuff that needs to be done instead of thinking about it, or reading about how other people are doing it.
It's amazing how much time we waste reading and thinking about stuff instead of just DOING it.
Don't get me wrong, I'm just as guilty as everyone else. I struggle daily to keep myself on task.
