Start by learning docker, you don’t have to selfhost anything yet, just learn to run a container, specially to run automated stuff. Then learn to build the images and run docker compose.
Also you could start checking any form or infrastructure as code. I usually hear about ansible and nixos.
This helps having a way to redeploy your services in any hardware easily.
Borderlands 2
I got into playing it yet again, mechromancer is so much fun when having full stacks of anarchy with a shotgun.
