Probably not exactly what you are looking for, but I’d recommend just starting to selfhost things. Have some old computer? Want to get a VPS?..

Something thats neat for selfhosting is pihole, if you feel up for it, go with docker as it makes things much easier in the long run.

Don’t be too afraid to break your software. It will happen eventually. And always remember that stuff deleted with rm won’t come back, thats what made me install a new OS on my VPS.
