I hope you will get more sleep in 2010. And eat better food, too. And embark on some regimen like meditation that will reduce your stress levels. In general, Sagittarius, I hope you will learn a lot more about what makes your body function at optimum levels, and I hope you will diligently apply what you learn.
That doesn't mean I think you should be an obsequiously well-behaved pillar of the community. On the contrary, what I'm envisioning is that by taking better care of yourself you will make yourself strong enough to run wilder and freer.
