A calm mind at peace is the most effective tool. We do not have control over what happens to us in life, but we do have control over how we chose to respond to those situations, and that is so empowering and wonderful. When you are worried, it is at that moment you must choose to not worry at all, freeing your creative mind and spirit to solve your problems instead.
