That&#x27;s interesting. I do the reverse. I have a trail of hundreds of mind maps and lists on paper, some of them probably recycled by now. I&#x27;ve always wondered if it would have been better to save them and review. I think I&#x27;ve lost a lot of work on some problems&#x2F;ideas I wanted to explore that way. Probably forgotten a good number of problems I was interested in to start with. Mostly personal though - professionally, my desk piles up until I&#x27;m forced to review the usefulness of each piece of paper (still, the &#x27;where&#x27;s that sheet gone&#x27; dance is common).
