After a particularly challenging learning environment, often the learnings feel obvious.
You've battled through a chaotic environment and emerged much wiser.
But when you go to write down or communicate what you learned, everything you can think to say is things you already knew, or were obvious.
Book learning is wildly different from experiential learning.
There is no way to substitute book learning for experience.
It's one thing to intellectually know something, it's another to feel it in your bones.
You can only feel it in your bones from experience.
The best way to learn is not by thinking, but by doing.
The only exception is if you take the time to think after the doing.
