I miss the sheer amount of time I sent as a kid wasting time on clearly pointless endeavors and having a blast with it. I distinctly remember spending an entire afternoon trying to see if I could jump-kick over the invisible walls outside of the castle in Super Mario 64. Realistically speaking, the game's physics made doing so entirely impossible, and even if I had managed it, the game would just glitched out anyway. Nothing interesting would have happened, at all. In a sense, I knew that even at the time, but I wanted to try anyway, and try I did.
Nowadays, everything I do has to have an end-goal. I like video games, but I often struggle with just... playing, without setting constant achievable goals for myself.
What I don't miss? Gym class. I was so, so, so painfully uncoordinated. I still am. I almost always forgot my shoes, which was in large part an executive functioning issue, but I... also wasn't exactly motivated to remember them? I was always kind of was relieved whenever I forgot them since it meant I had to sit out, even though I'd always get my ear chewed out over forgetting them again.
