My luck.

Pots of gold were never found no matter how hard I looked,
I have yet to find a mermaid after all of the fish I've hooked.
The pennies in the wishing well mustn't have been enough to pay the toll,
My four-leaf clover didn't bring enough luck to reach my goal.
The Yellow Brick Road never helped me find my way,
And after all the stars I've wished on ... you still didn't stay.
