Long-term knowledge is harder to notice because it’s buried in books rather than blasted in headlines. But its benefit is huge. It’s not just that long-term knowledge rarely expires, letting you accumulate it over time. It’s that compounds over time. Expiring knowledge tells you what happened; long-term knowledge tells you why something happened and is likely to happen again. That “why” can translate and interact with stuff you know about other topics, which is where the compounding comes in.
This is important. To try to increase your long-term knowledge and build on that with more information that you’ll retain.
The difference between expiring knowledge and long-term knowledge is obvious,, but I've never really thought about the real meaning of the difference
