Half Life: The Decay of Knowledge and What to Do About It
If we want our knowledge to compound, we’ll need to focus on the invariant general principles.
Half-lives show us that if we spend time learning something that changes quickly, we might be wasting our time.

It takes about 6,400 hours of class time and studying to get a 4-year degree. Assume that it takes you only 5,000 hours to master your field.
While you are happy that you've prepared for your profession, the knowledge you've learned is fast becoming outdated. We can safely assume that in 10 years, 50% of the facts in the field would be outdated. This means that for you, just to keep up in your current field, you'd need to learn 5 hours per week, 50 weeks a year.
When we consider the future of work, there are two trends we should keep a note of. They are:
Erwin Schrödinger was a Nobel prize-winning physicist. Schrödinger proposed a paradox in 1935 to illustrate a point in quantum mechanics about the nature of wave particles.

A cat is placed in a steel box along with a Geiger counter, a vial of poison, a hammer, and a radioactive substance. When the radioactive substance decays (it decays as a random process), the Geiger detects it, triggers the hammer, and release the poison, which kills the cat.
Until the box is opened, the cat's state is entirely unknown. Therefore, the cat can be treated as both alive and dead simultaneously until it is observed. If you try to make predictions about the cat's status, you're possibly going to be wrong. But if you assume it's a combination of all of the possible states, you'll be correct.
Really minute things don't obey Newton's Laws. The rule that we use to govern the motion of a ball or car can't be used to explain how an electron or atom works.
Whether it's the questions startup companies ask in meetings, or the quarterly earnings of a company, short-term, expiring knowledge has very little context if not paired with long-term knowledge.
If you intake more long-term knowledge by reading good books, you can be a better judge of which expiring knowledge to absorb and which to reject.
