Every six to eight weeks, go through your notes. If there’s anything in there that you haven’t looked at in the last six to eight week, delete it. Why? If you haven’t used that information already, you probably aren’t going to. Ever. The information might be out of date or you might stumble across a newer or fresher source.

You don’t want to become a digital hoarder. Why? As you collect more and more information, it becomes harder to part with it. You find ways to convince yourself that you’ll need that information for some reason. You’ll find ways to convince yourself that you’ll use it sometime in the future.

You won’t. Period.

An argument against noting everything down even if it's "just" digital and won't take up physical space.
