If there will be a fall of civilization soon, then what would you advise to do so as not to regret later?

I'm a regular guy, I'm about 23 years old, I work at a job with a flexible schedule, the job is more or less acceptable, although sometimes it's very annoying because of the extra repairs. Lately, I've been really wanting to go to festivals with cosplayers and stuff, but time is tight, and because of AI and data centers, there is even less time than there could be. And I never even went on a date, I constantly postponed everything for later, and now it seems to me that everything is lost.
