What strikes us here is not simply that learning continues—it's Michelangelo's admission that *mastery itself* becomes a doorway to deeper ignorance. A man who had already sculpted David, painted the Sistine Chapel, and stood as perhaps history's greatest living artist still felt like a student. This matters because we tend to believe expertise closes inquiry, but Michelangelo shows us the opposite: the more you create, the more you see what remains undiscovered. A surgeon with thirty years of experience still trains on new techniques, not from professional obligation but because every patient teaches her something her textbooks missed.
