This is what I try to do as well, and it works so well; it's very motivating to know that you have a comfortable starting place to come to in the morning. Another thing I've started to do whenever I don't necessarily have a bug is to just run our entire suite of unit tests. We are usually pretty good about keeping everything green across the board so it almost never results in anything worth fixing, but just typing _something_ is more often than not enough to get me into working on the next story or whatever.
