I got into horseback riding. I tell everybody it was the first thing I did in YEARS that was totally unrelated to being someone's employee, wife or mother. And, since a horse is a sensitive living creature, you need to be all there and really "present" -- without bringing anything from the outside world. If I'm spacey & distracted or unfocused, my horse knows. If I keep my head in what we're doing, he knows that too. There's something about working in unison with a 1000+ pound animal that just feels so terrific.
I tell everyone that my riding lessons are cheaper than a therapist and more fun than a personal trainer.
Good luck finding what makes you feel like YOU.
