I might be missing something, but the question itself seems to be false. I already am whatever I am. Both my masks and my behavior when alone are part of me. If some part of me does not fit me for whatever reason, I work to ditch it. If there is something I don't have and want to have, I work to acquire such trait. Attaching truth values to this seems silly. What do you mean by staying true to yourself (and the opposite)? How would you spot it?
