Don't be too hard on yourself and don't overthink it. Just grab the dough rope and start as if you're about to tie a knot. The rope isn't going to be long enough, so it's not going to be completely tied into a knot. You just start and then when you run out of rope, you just tuck the ends inside. It won't fully go into a knot. It's just sort of twisted. And these don't need to be perfect. What matters is that you tuck in the ends.
