汉译英,有点难度.

问题描述:

汉译英,有点难度.
:有一些东西错过了,就一辈子错过了.人是会变的,守住一个不变的承诺,却守不住一颗善变的心.有时候,执着是一种负担,放弃是一种解脱.人没有完美,幸福没有一百分,知道自己没有能力一次拥有那么多,又何苦要求那么多.

虽然不是百分之百一样,不过我很努力翻译的接近了.
When you miss out on some thing,that's it.Everyone will change,we can keep our promises but we can't keep our changeable heart.Sometimes persistent can be responsibility but give up can also be relief.No-one is perfect,therefore happiness will not be one hundred percent.Why ask for so many if we know we can't afford so much?
