Came here to post this one. I intentionally tried to train myself to do this about 10 years ago and the muscle memory came a lot quicker than I expected. It's a very secure knot and the sides hang to the side, not wonky like the ones most of us learned.

It took me a few months to nail it; jealous you got it more quickly than I did!

This was kind of like learning Vim. I struggled with how to computer for two weeks and lost the desire to learn literally anything else after mastering it. (I still prefer Vim with my plugins over VSCode!)
