That's a good goal. Mine is to get more in shape. I have little to no endurance when running, and I'm trying to build that up. And at the same time, my gym teacher told me it would benefit my health if I gained a few pounds. So I suppose I'm trying to build some muscle mass over the summer.
Oh, and another goal I have: to not pitch a fit or get frustrated when doing summer reading. I can't stand it.
