Good old Franky Planners
I worked at a college in the mid-1990s when I was introduced to the Franklin Planner system At that institution, the president loved them so much he made sure every faculty member who wanted one would get one free. I left that college and had to buy my own every year, so I've been buying and using one for at least 20 years. So I was glad to read this article. Although I put my scheduling on the computer now (Outlook, which interfaces with the phone), I still use the Franky planner as a back up, for meeting notes, for daily journaling, etc. The research shows it is best to have a paper planner. https://www.nytimes.com/2018/01/04/smarter-living/paper-planner-guide.html
