人类
1.Don t let the sadness of your past and the fear of your future ruin the happiness of your present.别让过去的悲催，或者未来的忧虑，毁掉当下的快乐。2.You are a part and puzzle of someone’s life. You may never know where you fit, but always remember that someone’s life may not be complete without you!你是某个人生命拼图中的一小块，也许你永远都不知道自己的位置在哪儿，但请记住：没有你，他们的生命是不完整的。3.When you cannot get something, it seems to be very important. And when you can get it easily, it seems trivial. This is human nature.当你得不到，它似乎就变得相当重要，当你轻易得到了，那它就无足轻重了，这就是
人类的本性。
