Last week I had a rather random thought come immediately at my mind. It was about the things I use and frequent daily. It was something like this:
“What has reddit.com provided you this week?”
I could not find a single thing that benefited me from looking at Reddit every day, I could not take a single insight from all the news and from the discussion that I read. Of course, what came naturally afterwards was to prohibit all interaction with Reddit.
Instead of visiting Reddit I shifted my focus and started reading books that I had currently on hold, and without needing to say, I have much more to say about these books than to lurking the web aimlessly.
I want to hold on a little bit on using it this question for other things (like for lesswrong.com) but I know that regardless I will do it.
“So what has x provided you this week?”
I agree, reading a book... and then reading a book on a different topic when you already had too much of the former... seems like a good approach.
Actually, the school seems to be designed this way, of course only if you assume that 45 minutes is the optimal time to spend with one subject. (Which is probably wrong, and also depends on age, subject, etc. But the idea of "focus on X for nontrivial time, then focus on Y" is there.)
