Death is so terribly final, while life is full of possibilities.
死亡是冰冷可怕的绝境，而或者却充满了无限的可能。
It isn't the end until we stop breathing forever. As long as we still can feel our heartbeats, we have the chance.
Spend more time smiling than frowning and more time praising than criticizing.
多花时间微笑，少花时间蹙眉；多花时间赞扬，少花时间批评。
From Richard Branson.
Smile is always better than cry. Praise is always better than criticise.
Even if you are not happy actually, it would be better if you can decorate your face with smiles, that can make you seem optimistic and sunshine.
