Found on an index card labeled “Ong’s Laws”:
The longer you wait to throw something away, the sooner you will have immediate and urgent need for it.
and from one labeled “aphorisms, etc.”:
When you add to what you know, does this mean that what you don’t know has diminished?
Of course not. Now what you don’t know includes how your new knowledge relates to other knowledge of yours as well as to what you still don’t know.
What you don’t know is bottomless and is getting deeper.
