I agree. I used to try to read X books a year, participate in Goodreads year in books, etc. This year I decided to stop consuming 90% of news and 99% of social media (mostly instagram) and try to read at least one 800+ page book per month (usually historical biographies).

After reading two of these larger books in 2021, I feel like (and this is nothing new or profound) that concentration really is a lost art and it just takes practice. I also feel like these large books probably help with retaining info because you spend so much time in them, being inculcated on the subject. It's kinda like a giant monthly experiment in SRS.
