Exactly, it was no longer mysterious for me after I had to prepare a written branching procedure for our team starting from how to branch off, commit, rebase to doing resets and working with reflog. While doing that I've thoroughly read the official docs, examined lots of examples, created a local repo with a couple of text files to test various commands. An then it became so clear and simple! Especially the reflog – so powerful!

So, my advice is to try to write some instructions for yourself for all the common cases you might run into during your work. It will not only help you realise what you actually need from git, but also will serve as a good cheat-sheet.
