They say that disappointment is the worst thing for the heart, but I say that in most matters, uncertainty is the far more dangerous thorn. For as terrible as disappointment may be, at least when one knows the worse, once can grieve over the ashes of a lost dream and move on and seek a new hope to cheer their way. But when one rides the roller coaster of uncertainty, hope does not last yet there is no chance to mourn as one repeatedly soars high with hope and then rapidly falls into the pit of loss. Trapped on the roller coaster of uncertainty one repeatedly cycles between hope and disappointment until the heart has neither strength for joy or grief.
