Writing Models Down – How Come It Works Better

Why is it that writing the models down on paper, instead of doing it in our head, is so much more valuable? Is there a podcast that goes into this please? Thanks. Sometimes I feel I spend more time working on my models than actually doing the task, but then when I do the task I feel so much better, like light and free, even if it’s only a 10 minute task like washing up the dishes in the sink.
