It may be hard for an egg to turn into a bird: it would be a jolly sight harder for it to learn to fly while remaining an egg. We are like eggs at present. And you cannot go on indefinitely being just an ordinary, decent egg. We must be hatched or go bad.
C. S. Lewis

Faith is the bird that feels the light when the dawn is still dark.
Rabindranath Tagore

Be like the bird who, pausing in her flight awhile on boughs too slight, feels them give way beneath her, and yet sings, knowing she hath wings.
Victor Hugo

A leaf fluttered in through the window this morning, as if supported by the rays of the sun, a bird settled on the fire escape, joy in the task of coffee, joy accompanied me as I walked.
Anais Nin

A bird doesn't sing because it has an answer, it sings because it has a song.
Lou Holtz

Intelligence without ambition is a bird without wings.
Salvador Dali

"Blackbird"
The Beatles

Blackbird singing in the dead of night
Take these broken wings and learn to fly
All your life
You were only waiting for this moment to arise.

Blackbird singing in the dead of night
Take these sunken eyes and learn to see
All your life
You were only waiting for this moment to be free.

Blackbird fly Blackbird fly
Into the light of the dark black night.

Blackbird fly Blackbird fly
Into the light of the dark black night.

Blackbird singing in the dead of night
Take these broken wings and learn to fly
All your life
You were only waiting for this moment to arise
You were only waiting for this moment to arise
You were only waiting for this moment to arise.
