如果不坚强 懦弱给谁看 标准英语翻译、、

Be strong,
as a wimp never has the audience.

To whom your recreance demonstrate, if you are not strong enough.

Nobody will be aware of your recreance unless you become strong
翻译字句翻译就没意思了 中译英也是一个道理

直译：
If you're not strong-minded, who are you going to show your recreance ?

If you are not strong, your recreance is for whom ?
