A good thing is I've been playing tennis I think every day for the last two months. I really haven't had a day off. I've been doing things that I did used to do.
It may take practice to think more positively and more compassionately, but just as you must train a puppy to behave the way you want it to, you must train your mind to behave itself. Otherwise, like the puppy, your mind will just make a lot of messes.
