You are me, 3 years ago! I’m diagnosed with ADHD and what you described is exactly how I felt when I was starting out. I even bought a RaspberryPi 4B+ CanaKit which sat in the box for over a year, just like you.

3 years later I have the Pihole, OPNsense router & firewall, Jellyfin, Traefik reverse proxy, and a bunch of other stuff too. My advice would be to start super small so you don’t feel overwhelmed. It is incredibly easy to get overwhelmed with all of this.

For what it’s worth, before I started hosting anything, I started with NextDNS. I just set up my iPhone and computers (then mac, now mostly linux) to use that service. It comes with super easy-to-use instructions and you can start for free. If you don’t like it, you can always just delete the account and it’ll be like you never used it at all. Very low risk but doing this will teach you about DNS. From there you can begin to move to a Pihole and Docker, if you’re comfortable.

Feel free to DM if you want. It’s a great community here and we’re all a pretty relaxed group.
