Count your blessings. Once you realize how valuable you are and how much you have going for you, the smiles will return, the sun will break out, the music will play, and you will finally be able to move forward the life that God intended for you with grace, strength, courage, and confidence.
Ultimately we have just one moral duty: to reclaim large areas of peace in ourselves, more and more peace, and to reflect it toward others. And the more peace there is in us, the more peace there will be in our troubled world.
