As others have pointed out, maybe look for a hobby.
Take baby steps towards becoming more involved in the things that youre passionate about. Housing affordability, the climate, and other things are on everyone’s mind these days, and maybe there’s something there that you have some strong feelings about. Look for virtual municipality or state/province public consultations about those things (e.g. new housing development consultations), and lend your voice to it. Meet new people with the same ideas.
Tldr, Try to make some of your free time into something self-directed, constructive and fulfilling (instead of passive algorithm surfing).
CloudFlared is the application you run on your server, and CloudFlare tunnels are what it connects with. You get the same outcome as a ddns but it functions differently under the hood. You also need a domain name for this I think.
DuckDNS might be a good option to start out with.
