Here is a bunch of articles and things that I have written over the years for download in pdf. I’ll add to them over time as I update and I will also try to make other formats in the future. Feel free to read and copy them, but just remember they are copyright to me.

This is the link to the video of exercises that is explained in the article on exercises. They are needed together. One explains the other. They are pretty useless each on their own.
