If you've never gone and built your own system, or started a network from scratch without a container based system, and you've relied on stacking your own environment for a long time, you might necognize it as you would any skill.

I'm sure I could build a shed, for E.g. I know to get the wood, the panels, the cement, and all the things I'll have all documented in front of me.

Then I will start, realize I forgot I also needed a permit, which I then found out I might also need to run power to it, so now shed has become something that doesn't feel impossible, it feels daunting

Why? Well, I don't build sheds, I don't keep building things that would allow me to have all the framework, project of getting my shed built. So, as with a homelab, take it one step at a time, and if rhe shed isn't the house, you're allowed to skip a few things and stick with what works for you.

I use homelab and self hosting as a passion, but I also have 25 years of networking and systems administration experience so docker and containers just made my normal, tedious job of building up complex network infrastructure, feel like a job, and my homelab and self host happens to be a hobby

Treat your homelab as a passion or simple hobby, or use it as a skill building tool for work

Overall it's just time, experience and expectations that either drive you forward or set you back
