I am not afraid of tomorrow for I have seen yesterday and love today.我不害怕明天，因为我经历过昨天，又热爱今天。The value of life lies not length of days.but in the use of we make of them.生命的价值不在于能活多少天，而在于我们如何利用这些日子。Courage is the ladder on which all the other virtues mount.勇气是其他美德攀登的梯子。Better to light one candle than to curse the darkness.与其诅咒黑暗，不如燃起蜡烛。
