I submitted a response but if i may give some feedback, the second portion brings up:
I am willing to pay a substantial amount for hardware required for self-hosting.
This seemed out of place because there were no other value related questions (iirc). Such as:
- I believe self hosting saves me money in the short term
- i believe self hosting saves me money in the long run
I'm sure you could also think of more. But i think it's pretty important because between cloud service providers and any non-free apps you want to use, it can be quite costly compared to the cost of some hardware and time it takes to set things up.
The rest of my responses don't change but if you're wanting to understand the impact of money in all of this, i think some more questions are needed
Best of luck!

That #1 is crucial. I see a lot of people get stuck in tutorial hell or burn out from doing other people's projects. Some tutorials are okay if you're just starting out but at some point switching to your own projects and challenging yourself is necessary
And since OP mentioned being on/off, i would also just say be consistent. Dedicate some time to work on your own projects so you're not forgetting stuff before it really sticks
