Even when a bird walks, one feels it has wings

It is a profound mistake to think that everything has been discovered; as well think the horizon the boundary of the world

become two wings of the same bird of prey.

A friend is one who walks in when others walk out

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

Intelligence without ambition is a bird without wings.
