Cover art for A Beautiful Lie lyrics by 30 Seconds to Mars

I thought it was about growing up.. The shedding of old beliefs, the pursuit for the truth. And how that hurts. So the author tries to go back to his "beautiful lie", "I've got to remember this is just a game", it's him trying to go back to that point. I can quite relate to it like this.
