I requested that data because for some reason, in my own experience, I've noticed the tendency you mentioned in your previous post as being strongest when I'm trying to avoid the internal monologue way of thinking.

If I try to avoid using words in my thought process, I often find myself walking around empty-headed for some reason. It's as if it's a lot harder to start a non-verbal thought, or something. I don't know.

When walking around with a lot of thinking time on my hands, I've found a lot of success keeping myself occupied by simply saying words to myself and then seeing where it takes me. For example, I may vocalize in my head "epistemology", or "dark arts", or something like that, and then see where it takes me (making sure to start verbalizing my thought process if I stall at any point).

Maybe I'm on a different topic though. Are you simply asking what you should spend your time thinking about, and I'm going into the topic of how to start a thought process (whatever it is)? This seems like an unlikely interpretation though because you said the problem is not having a pen and paper, which suggests to me that you know what to think about, but end up not doing anything if all you can't write or draw.

Sorry if this is pretty messy. I wanted to respond to this, but didn't have much time.
