No matter what has happened in the past, you have to believe that the best is yet to come. Even if life gives you a thousand reasons to be sad. You also have to find a thousand and one excuses to be happy. No matter how cruel the world is, keep a relieved heart, use your smile to dissolve all indifference, forgive all people and things before going to bed, live in the moment, be less dependent, believe that there will always be unexpected warmth on the way, and believe that someone will fall in love with your smile.
