William Butler Yeats Quote

What matter if I live it all once more?
Endure that toil of growing up;
The ignominy of boyhood; the distress
Of boyhood changing into man;
The unfinished man and his pain
Brought face to face with his own clumsiness;
The finished man among his enemies?—
How in the name of Heaven can he escape
That defiling and disfigured shape
The mirror of malicious eyes
Casts upon his eyes until at last
He thinks that shape must be his shape?
