Surmounted difficulties not only teach, but hearten us in our future struggles. It's hard to tell our bad luck from our good luck sometimes. And most of us have wept copious tears over someone or something when if we'd understood the situation better we might have celebrated our good fortune instead. What was hard to bear is sweet to remember. Joy is the will which labors, which overcomes obstacles, which knows triumph.
Problems are to the mind what exercise is to the muscles, they toughen and make strong.
A spiritually optimistic point of view holds that the universe is woven out of a fabric of love. Everything that is happening is ultimately for the good if we're willing to face it head-on and use our adversities for soul growth.
