This is all good advice but one thing it doesn't touch on is: which pen and notebook?
I like the pilot precision v5 pens because they come in a lot of different colors and the point is very fine.
For notebooks, I prefer the Leuchtturm 1917 series. They come with page numbers, a space for TOC, a pocket in the back for stuff, two book marks, and lots of different sizes and colors and page layouts.
That's important because the other important thing about hand notes for me is one book per topic, and keep them different colors because they will pile up and it helps with differentiating them.
