"Do oneself justice"

[nPlayerc]

Can this phrase be used in the following sceneario (I made it up) ?

A: "Why are you still doing this if you know there's no chance of success?"
B: "I just want to do myself justice."

Thanks.

Does not sound right.

"To do something / someone justice" is used to express "to give a full advantage" (like your photo does not do you justice), or to appreciate (he did justice to the steak).
