You have every thing, every hardship suffered by you, all will at some time in your life to come in handy.你学过的每一样东西，你所遭受的每一次苦难，都是会在你一生中的某个时候去派上用场。

You never know what you can do till you try.除非你亲自尝试一下，否则你永远不知道你能够做什么。

When you feel like giving up, remember why you held on for so long in the first place. ---每当你想要放弃的时候，就想想是为了什么才一路坚持到现在。
