For what it's worth 这句话来自本杰明.巴顿，给女儿的一封信的开头。

翻译为：我的拙见不一定正确。

解答如下

for what it's worth:(尤为避免显得傲慢)不管好坏，不管有没有用 （英文解释：If you add for what it's worth to something that you say, you are suggesting that what you are saying or referring to may not be very valuable or helpful, especially because you do not want to appear arrogant.） 

For what it's worth, my feeling is that ice in whisky is fine.

不管怎么样，我觉得威士忌放冰很好。

I've brought my notes, for what it's worth. 

不管有没有用，我反正把我的笔记带来了。
