I started using Notion this year and my Very Short Review is that it's incredible and everyone should be using it. My only complaint is that I want to use Notion so much that it has tended to be cluttered faster than I'd hoped when I first started using it this summer.
The point of this post isn't to get you to use Notion (although you can try it for free and you use this link for $10 in credit towards a paid account), it's to document an incredibly simple and effective writing template I discovered recently that's really changed how I write.
The template is based off work by Edward Tufte and the
tufte LaTeX package and in particular the
tufte-handout document class in LaTeX (and Rmarkdown!). I've used the Tufte-styled handouts for a few years and I think they're fantastic. In particular, the side-margin for notes, references, graphs, and other marginalia is something I actually adopted for hand-written notes much longer ago. I adopted the Cornell method between undergrad and grad school, and anecdotally it seems to have made a big difference.
The original purpose of Tufte's design, as far as I can tell, isn't the same as the purpose of the margin in teh Cornell method. However, the basic principle of dividing your writing space into two unequal columns -- one for primary content and the other for a secondary stream -- is the same.
When I write in Notion, the template I use is based on a synthesis of these ideas. First, I create a new blank page and set the page to fullscreen width. While Notion does have built-in notes and blog post templates, these don't match how I typically think about writing notes.
