21st Night started off as a complicated spreadsheet that I used when I was studying for some really tough standardized tests. I adapted it as an app to use with my tutoring clients, and my students saw some great results. So, I decided to release it to the world!
Here’s a poster of me from when I taught Western philosophy to thousands of Chinese people, during a brief stint as an instructor for a Chinese startup. It was a lot of fun, and I really hope to use those notes and slides again sometime.
