I love how the song is about her being so 'great' and shinning, but really the most greatness comes in what you can give to others and being a teacher and lifting others to shine, giving back to society.

Generally appreciating those who have and are there for you too.
Reminding that heroes come in something as simple, and (almost unnoticeable) taken for granted as those closest to you, don't need some superman to come 'save' the day.
