Lyrics
He said that if you want to talk about your ideal You need [the] power that corresponds with it Even without having an ideal to talk about, that day, I just gave it up

But seeing people living hard Getting heat from their ambitions Can't say as who I am now, who cannot think of A sin-sin-sin-sin-single thing to win Time to move, now

I want to achieve it, that is why I have to Do what it takes with this hand, changing The lenght of these feelings to the amount of heat I'm going to achieve it, regardless of its size I want to achieve it, I want to achieve it I want to achieve it changing the length Of these feelings to the amount of heat I'm going to achieve it, no matter how big it is!

I believe that is where (To achieve a big one You need to put that much guts into it) You can find (A footprint to this generation) What's really worth (Let us stomp it, yeah!)
