“8 Mile” from Eminem is a song is about the troubles one goes through trying to become a success.

“I'm a man, I'ma make a new plan; Time for me to just stand up and travel new land; Time for me to just take matters into my own hands; Gonna make it, can't give up now; Once I'm over these tracks, man, I'ma never look back …” — “8 Mile” by Eminem
