Oedipus Rex
Variant: I am Fortune's child,
Not man's; her mother face hath ever smiled
Above me, and my brethren of the sky,
The changing Moons, have changed me low and high.
There is my lineage true, which none shall wrest
From me; who then am I to fear this quest?

The truth is that I imagined every bit of good fortune that has come my way. But in my imagination I also invented a belt that would allow me to fly and had special permission from Congress to urinate like a bird wherever I wanted. I wake up every morning disappointed that I have to wear pants and walk. Imagination has a way of breeding disappointment.

Context: While many a lovely ship below sailed by
On unknown errand, kempt and leisurely;
And after each, oh, after each, my heart
Fled forth, as, watching from the Downs apart,
I shared with ships good joys and fortunes wide
That might befall their beauty and their pride…
