Every time I want to learn new technology I spend whole day just installing and reinstalling and then I end up with reinstalling whole linux, because 1 lil' thing doesn't work. Am I alone?

Nope. Just did that myself learning Docker.

The fun part is finding drivers. My challenge is always the NDIS wrapper for whatever build im making. It sucks having an awesome os on your rig and not being able to get on da net.

reinstalling​ the whole OS is kinda overboard

Maybe you should try VirtualBox:
0. install VirtualBox
1. create VM
2. install and configure OS
3. take snapshot
4. try your new setup
5. [revert to snapshot if needed]
This way you will not mess up your system and will be able to experiment.

Yep happens to me too. Should switch to vm but thus also sometimes don't work as it should.

How I ended up with an extra ssd just for "experiments" (so no real data /private /work on it) to simply reinstall/add another OS if something fails.

Not the "best way" but as Linux installs rather quickly (ssd +i7) I don't mind - and it's very simple
