I process ideas and concepts mainly visually, in forms, colors and movement entwining (the movement especially is the most important!).
Verbal thoughts occur, but they are more of a chorus, or chord, rather than one voice - there is always several aspects sounding out together, and it can be hard to pick the dominant one to verbalize for communication.
There are thoughts which have already been translated to words before and I can communicate then easily, but also deeper areas or newly occuring "movements" which are still only visual, and I have to put in a lot of work to put them into words.
There's more, but this is as far as I have pre-verbalized...
Only this - I once read a book that talked about minds as a rainforest, brimming with life and built in layers and impossible to fully grasp at once. I think that metaphor works pretty well.
I've been there, as well. Luckily (or something like that), I'm sufficiently poor to be noticably anxious about spending more than 200 EUR in one go, and with that managed to convince myself that now that I know the parts and their price, I can hold off until I have accumulated half the extra funds by saving (drew up a saving plan and everything as the last step of obsession, and then re-focused on saving).
That was in January. I have stopped tracking my money and actively saving for this by April, and now the new PC build is again just something I wanna do some day, but not right now.
Negotiating with myself to first work towards possible and reasonable, but ultimately unlikely financial circumstances, and then predictably running out of steam, is my go-to strategy for expensive stuff I really want right now, but don't actually require to fulfill a need. Works surprisingly well!
