"...There's a lot more to be gained from being grateful than you might think. Managing your outlook towards appreciation and thankfulness feeds the soul. It brings calm and contentment. It lifts your levels of happiness and hope. Gratitude will amplify your positive recollections about times past, and in turn sets the stage for optimism about the future."
