I am going to say: "finally, I'll take what I think I should have in life (money, power, etc.) from this life."
E.g. I'm talking to my friend and say:
I think I am not where I should be in life. I don't have what I think I should have had up to know. I think it is so unfair to be here in my life. But I'm confident I will take whatever that rightfully should belong to me from this life.
How should I say that in a natural way?
Once, an American friend told me I could say:
- I will finally get justice out of this life.
But the problem is that I cannot find any reliable source which explains the idiom "get justice out"! This is why I think it is something made-up or it is simply wrong.
Also, I've encountered the excerpt below:
I see the world through different eyes
Took these dreams to make what's mine
And we don't wait to take our time Like I said, I'll take what's mine [Source]
Then please kindly let me know if I can say:
- I'll finally take what's mine from this life. (I think this is a natural way to say that; if you see nothing wrong with this quote, then I have my answer. If you don't, then please let me know what's wrong with it.)
I am wide open to any suggestions.
