Things that did not fit into the Courses

I want to keep my courses as lean as possible. They should only contain the absolutely necessary, the essence of what I want to teach at this exact moment. But, as you can imagine, behind any lesson, video, image paragraph, sentence, or even word, there is a story to tell or a reference to show. In a book, these stories go into the footnotes. As a book and footnote lover, I want to repurpose this word and use it on this website for any add-on lesson to the lessons of my courses. I am happy to hear from you which future *footnotes you would like to read, see or watch.
