帮忙把以下中文翻译成英文

人活着很累，要为更好的生活付出很多。

幸福是每个人都想要的，而且想终身拥有的。

我们能做的就是，没有幸福时要去争取，得到幸福时就要更加的努力留住他！！

机会来临时，只需要你不假思索的抓住他。

只有亲身经历过痛苦，才知道幸福的可贵……

People live a very tired life, and should pay a lot for a better life.

Happiness is what everyone wants, and what everyone wants for lifelong.

We can do is to go forhapiness when there's no happiness, and try harder to keep it when you get it.

When opportunities come, you only need to catch them without thinking.

Only when you've experienced pain, you'll know the value of hapiness.
