Is it possible to say, "expose your true self?" I know that "disclose" and "reveal" are possible.

It's too early to expose your true self.


Of those three, "reveal" would be the most usual. "expose" is possible; to me it seems stronger (even more openly revealing) than "reveal".

(Watch out for "expose yourself", by the way, as it has a very specific meaning: https://en.wiktionary.org/wiki/expose_oneself .)

Haha!!! Thanks a lot.
