rhythm is an important aspect of music. If im not in rhythm, i can't build up momentum. I think what's really hard ast when you've switched your attention to something else, and then you come back to something, there's always this effort o get back into it. It takes me almost a full day or two to go, oh, right. Ok, ok. That's that way. So i end up having to write documentation for my future self - like i'm writing it to a stranger, but that stranger is my future self. My advice is to try to do things to completion, because then you don't lose a momentum in the first place.
