Back? Or to the Future?

I rarely ever want to go back or forward in time very far. My dreams of time travel are usually pretty utilitarian: go back in time (say, just before lunch) before I said or did the thing that was incredibly naive, heartless, short-sighted or just plain dumb, or forward in time to the point where I won't feel regret, embarassment or guilt for the things I did or said. And while I don't feel this way often, it would be extremely useful on those occasions.

I think I would use time travel the same way I use television: a way to watch something interesting, for as long as it is interesting, with the ability to change the channel/time zone at my whim.
