Unironically it’s been done for thousands of years and is called meditation. Once you’ve washed the bowls, picked the crops, clothes are clean, floors are swept, you have to figure out how to make the most of just sitting down for awhile. Though being bored today I think is fighting the urge to do something when there are infinite things calling for your attention, which I guess is sort of a modern meditation in itself.
I never really learned this skill. I can just lie down in bed all day doing nothing (apart from thinking), and not get bored. This trait is not very beneficial for productivity...
This is actually one of the reasons I love the beach. I lie there, close my eyes, listen to the sounds around me, maybe drift off for a minute, maybe listen to music, read a few chapters of my book. My beach days are usually like 3hrs about, though. I have friends that like to go to the beach at 9a and stay until 6p. That’s too much for me
