God damn depression sucks.
I used to turn everything into a game. I used to be able to use my imagination almost infinitely. Past tense.
I could do incredibly boring and monotonous work and actually make it kinda fun, by sort of half zoning out: I could pay attention to what I was doing, but I was doing it for another reason in my head. Sure, it was a delusion, but it was a damn productive one. Moreover, I was happier.
Long reading assignments turned into a Nintendo NES style platformer with an imaginary character running and jumping along the lines of text and letters (It worked surprisingly well and you'd be surprised the amount I retained from that). Hell, it provided organization as I made the text lines into little levels in my head. If you've ever played a lot of Super Mario Brothers one, or three, you can probably still remember the level setups can't you? That's how I retained enormous amounts of words in my head, in the same way you know the layout of one of those levels. I remember every level of Super Mario 3 on the NES and how to move/play best. I remember the order, etc. I remember where every hidden secret from those games is in the exact spot in the level, etc. Imagine if you could get through some important but BORING as hell, long document like that and organize it all in your head that way.
Yeah. That and a few more tricks are not easy or sometimes even possible for me to do anymore. Damn it, I want that back.
