得之我幸 失之我命 用英文怎么说？

这句话源自徐志摩的：“我将在茫茫人海中寻访我唯一之灵魂伴侣。得之，我幸；不得，我命。”

想要译好，必须结合着上下文看。网上的版本不少，就是百度知道里，也问过答过N会了。
Gained if lucky, lost if fated - 这个简洁，不错。
My fortune to gain it, my destiny to lose it. - 也不错

It's lucky for me to get and doomed for me to lose.
It is lucky if I got it, It is destiny if I lost it.
Lucy my gain, forture my pain.

我自己的版本：
It's my fortune to have it, it's my fate to lose it.

或干脆
Fortune to have, (or) fate to lose.

用fortune不用lucky，是因为lucky有纯运气的因素，而fortune不仅仅是运气，还要努力。这个前面的句子相映。

get it would be my fortune,lose it would be my fate

Fortunately I have lost my fate
