The real trouble here isn't that we lack opportunity—it's that our beliefs calcify so quietly we mistake them for facts. Les Brown's wisdom cuts deeper than mere cheerleading because it names something we rarely admit: the moment we accept a limitation as permanent (I'm not the math type, I come from the wrong background, I'm too old), we've already done the work of closing the door ourselves. Watch how a child learning to read encounters the same difficult passage as an adult who's decided they're "not a reader"—the difference isn't in the text, but in what each person has already concluded about themselves. The boundaries that seem fixed are often just old decisions we've stopped questioning.
