Desire, choice, birds

In 'Scarlet Tide' Elvis has a little bird ('I thought I heard a black bell toll/A little bird did sing') say: ‘Man has no choice when he wants everything.’ I see what the bird means, I think; but at the same time I wonder about the voracity of desire necessary to be able to say, truly, I want everything. It would annihilate choice, of course; but with such appeitite choice would be an irrelevance -- or more, a positive irritation. 'I want everything ... except the power to choose. It is this latter that erodes desire in in the first place.'
