FWIW, journaling has been useful to me. I&#x27;ve run into bugs and thought, &quot;I know I hit something just like this before. Oh wait, let me look through my debug journal and see if there&#x27;s something in there!&quot; And often there is. It saves me having to do web searches or guess and use hunches. I can always fall back on those things if it&#x27;s something I haven&#x27;t seen before or is manifesting in a different way.<p>I&#x27;d go even further and say that I&#x27;ve often wasted time chasing down a hunch that was completely wrong.
