I honestly, truly don’t understand how “being yourself” applies to social interactions. I mean, I’m a nice guy and I’m well liked, i.e., people want to hang out with me, but if I were to truly be myself, I’d be universally hated, or at least avoided. Heck, even if I suppressed half of the things I’d like to say/do, I’d wouldn’t have any friends. We humans modify our behaviors–largely unconciously–to fit better into our chosen social settings. People who can’t do this at all are probably mentally ill. And I’m not saying that in a mean way; they’re actually sick and deserve empathy.
For me, being likable is largely about what personality quirks I’m able to suppress. I’m a logophile, but I don’t use words like “logophile” in conversation. In fact, I try to stay under two syllables in conversation, and I don’t use archaic terms if there’s a modern (albeit less specific or lovely) alternative. People will like you far more if they believe they’re smarter than you.
It helps TREMENDOUSLY to be funny, specifically funny in a light, witty, easy to digest sort of way. I’m naturally dry and sarcastic, but to be likable I have to be more generic (think NBC sitcom “wit”). This is easier anyway, since it requires really no thought. There are a couple of people I know who can appreciate a more cerebral wit, and I greatly enjoy their company.
I like to have meaningful conversations about life and art, but I don’t know anyone IRL who enjoys these types of conversations; they just glaze over when I mention anything that isn’t on TV. Again, to each his own. I enjoy a little TV too, I just like books, poetry, etc better. So, instead of forcing people to listen to my interests, I choose more mainstream topics and let the other person take the lead.
Along that same vein, I avoid talking too much about myself, and I’m careful to speak in terms of other people’s interests. If I know someone is a hunter, I’ll ask them if they’ve done any hunting lately. Big bonus points if I can work a little complement/self-deprecation twofer in there (“You’ve already bagged three giraffes this year?! Man, I’d be happy if I killed one!”)
In short, just assume that all people are desperate for someone to listen and care about what they have to say, and they appreciate an easy laugh as often as possible. Try to be relatable and relaxed without being condescending or aloof.
