Think of all the beauty still left around you and be happy.
Living life is being able to see the beauty in every situation, even the most ugly of situations. For in every death in life, there is always a new birth if we choose to see it. If we choose to look at life as ugly, stressful, and so forth, we will only see the evil that life has to offer. When we continue to look at the bad, the only things we will see in our lives are things that we will consider bad.
