The thing in this post about curiosity isn't just a lemmy/online thing.
The vast majority of people are mainly interested in themselves. Like - if you have trouble on dates, making friends, getting along at work, anything to do with people in general - approaching them with a sense of sincere curiosity will completely change things overnight.
Get people to talk about themselves, be supportive in your discussions with them, and shut the fuck up wherever possible and suddenly you're interesting, a good person, kind, whatever - traits you've done exactly fuck all to demonstrate, but that people will swear are true because you seem interested in them.
It's fucking bonkers but it's true. Curiosity can change your world.
