When it comes to wings, we often think of birds and butterflies flying freely in the sky. However, wings can also represent motivation and hope, which can help us to soar to new heights in life. Without wings, we may feel stuck and unable to move forward, but with the help of motivation and hope, we can overcome any obstacle and achieve our goals.
