Knut Hamsun, failed poet? 

"I am angry with myself for the collection, but it cannot be undone," Knut Hamsun wrote about his only collection of poems, The Wild Choir from 1904. It is a harsh judgment of his own poetic work, but one he has largely come to share in since. Hamsun's attempts to work outside the novel genre have consistently been met with a certain coolness.
