Time to yourself?

What are your all's thoughts on doing something on the sabbath, that doesn't necessarily put God first. Though t's not necessarily something you don't get to do during the week, you just to relax and take time for yourself. I don't know, things like sitting outside listening to one of your favorite non christian songs. Going to a friends house and deciding to play a game. Going for a walk, and pick a friendly game of basketball or any other physical activity. Personally, I'm sort of torn on this topic. The "rules" are not spelled out black and white and therefore I believe there is some discretion that must be taken w/ various activities. Only you know how close you are w/ God and only know when you can feel Him telling you that certain things probably aren't the best thing to be doing...
