OK, it's late and I just thought of this... so, everyone has these negative thoughts, right? What if when we were thinking of them, we gradually let them float farther and farther away until they had less and less 'power'- envision a flying a kite on a beautiful spring day- it's cool and breezy, clouds like cotton candy are scattered across the sky. Your negative thought is the kite, but you're caught up in the moment... the wind is tosseling your hair, you're laughing and running with a childhood friend, you stumble into one another and the next thing you know your kite is GONE. But you're having too much fun to care. You tumble onto the ground, giggling and tickling one another- NEVER giving the kite/negative idea another thought.
OK- def. LATE!

Oh, well. Here's one I do use regularly. When I'm ruminating over something ridiculous, I physically shake myself like a dog and say, "Out, damn thought, OUT." I know, contrary to the original Lady Mac's predicament, but it works for me... and it makes me smile

Peace-
this lady has GOT to go to bed,

BTW- after posting, I reread this and thought of the phrase, "Cut the Kite"- this made me chuckle even more... def. time to go to bed! HA.
