I&#x27;m a pens-and-notebooks power user, and I know exactly what you&#x27;re talking about.<p>The trick is, whenever you&#x27;re writing anything, add notes for your future self to make sense of whatever you&#x27;re doing. It&#x27;s like adding comments to explain your code.<p>It&#x27;s a little extra effort and bookkeeping but it makes old content so much more valuable!
