I am a person who writes proposals and teaches, although not often. I always had a hard time planning content and writing materials, and as a countermeasure, I often filled in the missing content by drawing pretty shapes or fancy diagrams. After listening to this lecture, I learned what had been frustrating me and was able to receive good teachings to improve. This lecture is worth the money, and I am grateful that the course period was extended after I gave my opinion on Facebook. I will watch it again whenever I have time. ^^ P.S. The "Wall Street Journal Infographic Guide" that you mentioned during the lecture also arrived today and I will enjoy reading it. It would be better if I compared it to the "Dashboard Design and Data Visualization" that I had before. ^^
