One of the best pieces of writing advice I saw somewhere was:
Don’t know what to write about? Write the blog post, or article, or essay, or book that you wish existed
This could be curating a list of articles or ideas or connecting ideas in a way that have never been connected before. Or it could be synthesizing / reframing an existing idea or piece of writing in a way that makes sense for you. It can be so many things but I like the idea of asking “what do you wish existed?” … and then go write it.
