Yeah, I think reddit is going to die (if only due to the process of enshittification and the consequences of going public) but the idea of a mass exodus is a bit of a dream. Anyone who has had a conversation going on in one channel, and then have a mod tell them to move it to a more appropriate channel should know this. The conversation doesn't move, it just stops 9/10 times.
But we shouldn't be preoccupied with reddit as a community. Give what you can to Lemmy and enjoy it for what it is, not wishing it to be reddit.
I'm a very flitty sort of person, and can be pushed off balance decently easily. My job is pretty fast paced, so I can't just go for a walk or meditate for 10 minutes. So my rule is to not focus on everything coming up, but just focus on what's directly in front of me. Which, yeah, I know sounds dumb but it honestly does work.
Instead of thinking "Oh, that line of customers is long" -> "Oh god I'm not going to be able to serve the customers fast enough" -> "oh my god they're going to leave and I'm going to get in trouble for not being fast enough."
I don't even acknowledge the length of the line. Look directly ahead, and focus on what you're doing right now. Shit will always be coming in from every direction, but quick steps make for shorter journeys.
Outside of work, hobbies, crochet, gardening. Getting in touch with nature is a big one for me.
