Yes, this. I have no problem adding, rm-ing, branching, making and accepting PRs, etc. These are what the overwhelming majority of git for dummies tutorials cover. (I've even paid for a very well-known and well-reviewed course and completed it.) And, these photos upthread are fantastic for that initial git-101 progression.
Then, I eventually landed my first tech-sector job and still haven't picked up much more since. My solution to every ounce of apprehension is deleting and re-cloning out of paralysis and fear.
I find great difficulty in being able to glean a repository's "environment" in a sense analogous to gleaning the environment of an initially compromised machine (the foothold) when you've popped a fresh shell on a boot2root box. (I thank the digital gods for IppSec and his hands-on videos that teach you how to clear up the fog of war around you!)
