Once I screenshared with a colleague of mine who was kind of an interesting character and I don't think I ever saw such a mess ever. He had literally a hundred notepads open with little bits of random text written in then, there was a bigger one where he documented his day like "9:27 I asked Jim about global variables", and of course his browser was maxxed out on tabs. It took him over a minute to find the thing he wanted to ask me about.

Of course, he was also a person who left a 10 paragraph comments his own PRs. Yes, not a reply to someone else's comment. He commented his own work, like "I still have to think about this part. Maybe I'll do it a different way. Let me think about this when I come back from the loo." (Again, no exaggeration) I don't think he ever finished a ticket before he was let go.
