I noticed early in my 20’s that my social anxiety had gotten to a point where I couldn’t casually chat with random people. So I made an effort to do it anyway even though the results wouldn’t be favourable for a while. It took a few years before I noticed it didn’t take much of a push any more to start. I’m 40 now and while I still don’t enjoy talking to strangers, especially when just making meaningless small talk, I at least don’t have a wall of pre-dread anymore to climb in the case that I do need/want to talk to a stranger. Like if they dropped something, or if I want a product in a store that is not currently stocked on the shelf.
