There's often a sting that comes after new learning.
You think, Why didn't I know that before.
That's often the humbling part of learning.
In environments where new learning is embraced along with the discomfort and error it often brings, the sting is not so strong, but in environments less open to new learning, the sting is greater.
Similar to when a bee sting subsides, there is increased wisdom after the new learning. You know better how to avoid the hives that exist on your learning pursuits. This is yet one more aspect of the mostly joyous, but sometimes troubling path that new learning takes.
