Haha unfortunately I don't have any :)
I've gotten through high school, college, and 12 years of post-career without literally any note taking. I've come to realize that I am no longer able to be as spongey as I used to be with academic style learning (non-exploratory) and I just decided one day to start taking notes under the idea that if I rephrase what I'm learning I will better retain it (based on the adage that if you can't explain something then you don't actually understand it).
So my notes are mostly focused on non-literal summaries of what I have gotten through using my own words and phrases. So far that seems to have helped but I've only been at it for a few months so I don't have much data points.
The real test is now as I"m learning Linear Algebra and computer graphics, which I tried learning before and I don't remember much of anything from it (even though it was only a year ago).
