Keep yourself optimist and smiling. Everybody will also smile in return. This optimistical environment is positive and you must be the first one to build it. You ll be the one who will determine how the surrounding environment will be. No one else.
Nature is never wrong.
Try looking at it with different eyes. Everything is prettier than you think it is. For me, a butterfly is more than a butterfly. We should be born very old people and, during life, improve body and soul, until we become babies and then, die, entering in our mothers uterus. It' d sure be much more beautiul.
