Working / reading retreats

John Carmack says:

Once or twice a year I go on "working retreats", where I lock myself in a hotel room for two weeks with no internet connection for completely focused work.

Many-many years ago when I read about Bill Gates' twice-yearly "think weeks" I immediately realized how much I needed such a thing. Either reading or working would be fine. Just go completely offline, no phone, no emails, no feeds, no internet, no TV.

I'll try do do one full offline weekend for practice sometime. :)
