If you are not in a tech field, what got you into self-hosting?

I'm an English teacher who wanted to "cut the cord" wherever I could, so I started learning about domain hosts, containerization, .yaml files, etc.

Since then, I've been hosting several pods for file sharing and streaming for many years, and I'm currently thinking about learning kubernetes for home deployment. But why?

If you aren't in development, IT, cyber security, or in a related profession, what made you want to learn this on your own? What made you want to pick this up as a hobby?
