Another way to think about New Year's resolutions is...not necessarily how we want to limit ourselves or to change something we feel guilty about -but how about...how we can do more of something and how we can stop limiting and start liberating.
When negative thoughts come in, ponder the opposite -one of my favorite sutras from the Yoga Sutras.
When we allow negative thoughts to take over we tie ourselves down. Freeing ourselves from what stops us becomes so important. Unreal fears often stop us in our tracks and in our modern lives we learn to feel fear for no reason. We stay in an unnatural fight or flight mode and we don't get to feel the unbound potential that is...limitlessness.
