There is a trap that every note-taker falls into: collecting material without processing it.
You save 200 articles. You highlight everything. You have a system. But you never write.
The collection becomes the procrastination.
The fix is uncomfortable: delete what you haven't touched in 60 days. If it was important, you'll remember it. If you don't remember it, it wasn't load-bearing.
