Electrolytes and resources:
It is a variety of study subjects in the school of life. It has no time or place, no chapter or book.
It is available to every person, and every day it contains more than one exam, and its materials have not been subjected to planning or preparation, and it has no curriculum.
It comes and goes, disappears and settles, changes and is renewed... This is how its materials are as I experienced them.
Resources are study materials imposed by life experience and written by life experience, and life remains the mother of schools.
