Still love to, am just a mother so it’s not as often.
I think a big part of it is having open energy. Keep your head up, keep your eyes open. Look around. Make eye contact with people. Smile. You don’t have to have anything really witty to say, but the more observing you are the easier it will be to find a way in to having conversations. It also makes things more enjoyable if you don’t end up finding anyone that you really connect with. It’s fun to just be around people and watch (I say as an ESFP lol). But, it’s surprisingly easy to just join a convo or add your two cents. I’m fidgety so I like having a non alcoholic drink in hand.
I’d say, if your reason for going is to see the artist, don’t sweat about connecting. Just have as much fun as you can once they start!!
It’s really a confidence boost to go out and do things alone and still have a good time!
