Enjoyed this post. I always look forward to your Saturday newsletter. Robert Greene, Ryan Holiday, and Billy Oppenheimer swear by using physical notecards instead of a digital note taking tool. They argue that handling the physical index cards repeatedly as they manually sort them gives them more familiarity with the content. What would be your argument for using Obsidian over an index card-based system? I find myself torn between the two methods – I like the arguments for index cards, but the efficiency of Obsidian and the ability to search and link are undeniable advantages.

Thanks!
