Everything. Everything that happens to you, everything that gave you a smile, people, meaningless things; everything, everything must be appreciated. A person realizes the value of something after his loss. Sometimes you beg the heavens for death, and sometimes — while kneeling — you read every prayer learned before the icon for the sake of salvation, for the sake of life. Every thing, every moment, every second — everything must be appreciated. There will be dark corridors of life when this is taken away from you. Everything will destroy, perhaps life. Everything will be shattered, all memories and moments; you can't get them back. Then you will give your life for the last time to look into the eyes of the person you value most. A happy person is not one who did not have dark corridors of life, a happy person is one who passed these corridors, no matter how difficult and painful it was. After darkness there is always light, for after trial there is always reward. Light is happiness.
