The thing is, if you set a lofty goal for yourself and you meet it, then what? Raise it for next year? Where does it all end? At some point, you become a slave to your self-imposed goals. Maybe it's not such a bad thing to fall a bit short. It'll be a reminder that these types of goals are ultimately meaningless. If anything, you can be a little proud for having the sense to not let them get in the way of your real life.
