For me it's been about slowly learning, building, and re-building what I have, as I have gotten more knowledgable.
I started with a Windows laptop running 24/7. Learned about Docker Desktop and ran Jellyfin and the *arr stack on it.
I had Linux running on my PC, so as I got more comfortable with CLI, I decided to migrate the server and everything on it to Ubuntu Server. Learned to navigate on SSH better, learned more about networking and expanded the server with more services like Nginx Revers Proxy Manager and exposing services online.
Then I upgraded my hardware and installed Proxmox on the new machine, to better manage that and the old laptop. Slowly getting better at backing up at different levels, heightening security and so on.
Guides are good, but I find experience and steady knowledge building is a better way to grow and not get overwhelmed or burned out.
