1.  英译汉：

1.1.  "Success is not final; failure is not fatal: It is the courage to continue that counts." -Winston S. Churchill

暂时的成功和失败都不能定义一个人，关键是看这个人有没有继续前进的勇气。

1.2  "In the end, it's not the years in your life that count. It's the life in your years." -Abraham Lincoln

生活的质量比长寿重要。

1.3  "The greatest glory in living lies not in never falling, but in rising every time we fall." -Nelson Mandela

失败并不可怕，失败后有勇气及时站起来才是令人自豪的。

2.  汉译英：

天下只有两种人。比如一串葡萄到手，一种人挑最好的先吃，另一种人把最好的留到最后吃。照例第一种人应该乐观，因为他每吃一颗都是吃剩的葡萄里最好的；第二种人应该悲观，因为他每吃一颗都是吃剩的葡萄里最坏的。不过事实却适得其反，缘故是第二种人还有希望，第一种人只有回忆。

There are only two kinds of people in the world, when they have bunch of grapes, first kind of people will pick the best ones to eat first, the second kind of people will pick the worst ones to eat first.  You may think that the first kind of people are the optimistic, because they eat the best ones; and the second kinds of people are the pessimistic, because they eat the worst ones first.  However, the fact is the opposite than what you think. The reason is that the second kind people will always have hope, and the first kind of people will only have memories.
