Wanted to share a song from the coolest dude on the planet.......David Bowie.....Thursday's Child, off his "Hours" album from 1999 is my favorite Bowie song.
It seems to me that this song is about Bowie himself, saying that he always felt slightly out of place. He was a person with gifts and potential who never quite got off the ground, breaking his life in two (into the man he had potential to be , and the man he actually became), he feels like he was born in the wrong time, etc.
Then, he speaks of something that gives him hope. A reason that he no longer regrets his troubled life. He says "throw me tomorrow", as if tomorrow is a life preserver thrown to rescue a drowning man. For all of the hardships of his life, comparing himself to a Thursday's Child, he is now glad to be here because of his love, (the girl).
Also I think there is a component that speaks to age as he looks in the mirror. Yeah, he's getting old, but that is the past and he has new life now with his love.
Also, it may be that his song playing on the radio represents the success he's had in this life, but he knows it's really superficial (Mirror symbolizes this), and it doesn't satisfy him in a deeper way like the love he has with his girl, who is the focus of the video.
"Thursday's Child" does indeed mean "One that will go far". In this song, he reflects on his entire career, and his mistakes. He's telling himself (in the video, he tells a younger-looking Bowie he sees in his reflection) that no matter the mistakes he's made in his career, he's gone far, and he doesn't regret it.
Anyway watch the video and then draw your own conclusions
