Just thinkin!
The Ancient Greeks and Romans had neither formal/structured education nor credentials.
Yet reflect a moment on how Plato, Homer, Sophocles, Aristotle, Pindar, Archimedes, Cicero, Tiberius, Virgil, Caesar, Vitruvius; among hundreds were able to sustain themselves.
Think how deprived and lonely those poor souls must have felt w/o degrees to prove their worth.
How did they ever manage to survive and thrive????????????????????????
