Always forgive your enemies; nothing annoys them so much.
You are always a valuable, worthwhile human being — not because anybody says so, not because you're successful, not because you make a lot of money — but because you decide to believe it and for no other reason.
可持续性不是一种选择;它是我们对后代的责任。
根本不稳固必然会央及枝叶。行为不守信必然会损害声誉。
