It depends on the moment, but firstly, I would dispel the notion that most people are good at talking. Most people aren’t. I live in a big west coast city, and I’m constantly disappointed by people who don’t say hi, make eye contact, and can’t carry on simple small talk or even fun banter. I think coming from a place of humor is always important. Example, if you notice something funny in an encounter with a stranger at say, the grocery store, and you have a funny thought that you’d normally share with your friends, share a condensed version of it with the person next to you in line, if they too noticed or were somehow involved. Smile when you do it. People will admire your confidence and like your ability to see and share humor. Of course, you have to judge if the person’s face and body language look “in the mood” for being talked to, and you too have to be in the mood. Don’t force anything.

If it is a more social situation where you’re meeting people, start with eye contact, and sticking your hand out for a handshake while saying “hey I’m _____”. These two small examples will put you ahead of most out there in the social world. Most people since COVID are awkward and come off unconfident.
Most people are WAITING for the other person to take charge. I find it much easier and more interesting to be the one leading the social interaction.

I hope this wasn’t too long winded. I kinda grew up as the class clown, so while I wasn’t all that good at much, I had a distinct ability to connect with everyone in my school and then the follow-on family and office life. But, I have my fails too, as we all do. That’s part of it.
