There are wings hidden in every story.
Maybe it's the "It's okay" from a stranger when you are frustrated, a little persistence that you hold on to when you are confused, or a cup of hot soup that slowly warms up in the cold night - they are as light as the wind, but they can help people slowly stand up from the mud and take another step forward.
These scattered, soft moments are the wings given to you. You don't have to fly very high, it's enough that it can take you out of the current difficulties.
Purpose: Everyone who is in trouble or confused deserves to be gently lifted up. Every story in the book hides a power like "wings" - it may be the kind helping hand of others, the small persistence of oneself, or the inadvertent warmth in life. These powers do not have to be earth-shattering, but they can gently help people get up slowly from their downturns, learn to move forward with courage, and finally find their own strength to fly forward.
