Writing stuff down helps me remember the good times and that the bad times don't last. It shows growth, from the way I write to the way I think. And it's humbling to see my ideas strewn about a piece of paper and realize, they're not as good as I think they are.
So, maybe the tech overlords "hate this one trick". ha.
I do wonder if more people started journaling if the world would become a better place. not a scientist, so I don't know how you'd even prove that. but, anecdotally, journaling is just as effective as therapy for me.
