I won't even pretend this is good poetry, but the message is valid:

Leap

A man with perfect pitch who will not sing and doesn't play;
a woman of great beauty who will hide herself away;
another woman blessed with brains who sets her sights too low -
so many unfulfilling lives, but how are we to know?

Unless we spread our wings and try to leap from where we are
we'll never know if we can fly, or if we can, how far.
Unless we test the limits of our courage and our art
we all live little lowly lives, and lose before we start.
