I take most of my notes in Gregg Shorthand. Its helped me a lot. Now I’m teaching my son to write the script with this 1955 edition. You can get it on Amazon for next to nothing. Its wonderfully anachronistic with its advertisements for coal heating tune-ups and hotel rooms for 4 dollars.

The hardest part of learning shorthand is the few words in the writing/reading practice that just don’t make sense no matter how hard you try (and are so obvious once you find out – like most bugs). I’ve made some recordings so that won’t be a problem. Here’s a link to the lesson 8 and 9 readings. I’ll post the earlier lessons on request.
