如何英语翻译：年轻是我们的资本,但是青春没有承诺？

楼上的译法显然是不对的。 年轻是我们的资本 youth is our asset 青春没有承诺是什么意思，是年轻人总是轻易作出承诺但是不会遵守的意思吗？这样的话，大概可以翻成 young people make promises they can't keep。不过意境上跟原文还差一些

Youth promise us nothing but itself.

Youth is our capital, but didn't promise youth?

Being young is our capital,but there is no promise for youth

Being young is our capital, but the youth has no promise.

we can take younth for grand ,but whether it has promise?
