For me this is less about “being yourself” and more about not overly bending on your values to please others.
We are communal beings, and sometimes that means you have to act in certain ways to get along with the group. However, you should not have to compromise on the things that are most important to you in order to get along with the group. If you do constantly compromise, you’ll probably be liked, but you may never find YOUR group and always feel a bit like an outsider.
(If your friends like to say “that’s fire” And “yeet” and you don’t, that probably shouldn’t be a dealbreaker. If your friend group always expects you to drink when you’re hanging out and you don’t like to drink, then it’s probably a sign the fit isn’t perfect. Try not drinking around them and see if they accept you or else if they push you out and create room for you to find a different group. It’s scary to do, but results in deeper relationships in the long run.)
I was at a Meyers-Briggs workshop one time (company-mandated) and the facilitator said something that made a lot of sense to me: “At any given time, your personality is about 33% who you want to be, about 33% who the people around you want you to be, and about 33% who you really are”.
I think we adapt based on our context.
