It is not the point, whether or not there was a difference noticed. You will be the only soul alive that realizes all you may do, or not do. So taking that into consideration, never disappoint yourself. In everything do your best, noting more, nothing less. Realize that your best will fluctuate as the seasons do, sometimes your best may not seem as if it is best. Set your sights on an inner knowing rather than any outer confirmation. In our heart of hearts we know when our best has been done. Listen to your heart, for it is the truest guide you will ever encounter. It is tapped into the Universal mind.
