Lewis Levy says :

We're all faced throughout our lives with agonizing decisions, moral choices. Some are on a grand scale, most of these choices are on lesser points. But we define ourselves by the choices we have made. We are, in fact, the sum total of our choices. Events unfold so unpredictably, so unfairly, human happiness does not seem to be included in the design of creation. it is only we, with our capacity to love that give meaning to the indifferent universe. And yet, most human beings seem to have the ability to keep trying and even try to find joy from simple things, like their family, their work, and from the hope that future generations might understand more.
