The real sting here isn't that self-teaching beats classroom learning—it's the distinction between *sufficiency* and *abundance*. A formal degree secures your paycheck; it solves the immediate problem. But self-directed learning compounds quietly, letting you spot opportunities others miss, speak with authority in unexpected corners, and pivot when industries shift. Consider how a mid-level accountant who taught herself data analysis became irreplaceable during her firm's digital overhaul, while colleagues with only their CPA credentials scrambled to catch up. Rohn understood that one path closes doors from above while the other opens them from within.
