You know the meme that goes: "Be yourself. No, not like that."

It is possible for someone to have a goal of changing themselves into a person who can fit in socially, and be effortlessly comfortable while doing so. After building the underlying skills, they know how to navigate social situations well enough to intuit how much honesty and revealing is appropriate for a given situation, and can roll back "fake it until you make it". They can accept surmountable social penalties for the comfort of less self-filtering and chance to have more meaningful connections.

"Be yourself" means to change yourself, and then stick the landing.
