I'm often walking to somewhere and I notice that I have a good amount of thinking time, but that I find my head empty. Has anyone any good ideas on useful things to occupy my mind during such time? Visualisation exercises, mental arithmetic, thinking about philosophy?
It depresses me a little, how much easier it is to make use of nothing but a pen and paper, than it is to make use of when that is removed and one has only one's own mind.
How often do you think in words, and how often in visuals, sounds, and so on? Do you normally think by picturing things, or engaging in an internal monologue, or what? Or is the distribution sort of even?
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
