I've told this story a million times. So sorry if you heard it before.
When my 1st wife was pregnant she came home and said so many woman were pregnant at the save time. I said I bet it's not any more than usual however you are pregnant and now you're seeing all these other pregnant women. We got into a big fight!
The point is, sometimes just doing stuff will pay off later.
Practice dividing the octave up into 3 parts and don't worry about why. I can do it very easily and if you can't then you should so we both can do it, think about it and talk about it.
