Cover art for The Giant's Drink lyrics by Gatsbys American Dream

Other than the title, I don't think this song has anything to do with Ender's Game.

I think the song's saying that you should just man up, be yourself, and live the life you want to live. We're constantly told how we should live, and realizing that you don't like the way something is going and making the change is hard. I'm really reading between the lines, but that's my take.
