This. Maybe even more than 99% of the time you are fine. It's okay to struggle a day with a rare problem every now and then. Just don't be scared of it. There are enough resources out there to research them when you need them.

Where I still get nervous is when I force push my branch after a rebase, even if I know I am the only one working on it. But this is also one of these examples. If I remember correctly, there are other options to sync your remote after you did a rebase, but force push is just the easiest. So I rather take 5 seconds to make sure I typed exactly what I wanted and that everything is fine and that just works.

Edit: I was just brainstorming a bit about it and thought that probably some of the unknown magic git features were just implemented by a motivated dev that just wanted to explore what's possible. But on the other hand, there are most likely some very very obscure configurations and edge cases in the wild where people actually need those features. But most people will likely never need them, so I myself won't bother understanding "everything"
