Song meaning of Believer by Imagine Dragons

Okay, let me break this down for you. So first things first, the singer is fired up and tired of things being the way they have been. Second things second, he doesn't want anyone telling him what he could be, because he's the master of his own sea (metaphorically speaking, of course). He talks about how he was broken from a young age, but took his sulkin' to the masses and wrote his poems for the few that could appreciate his art. He sings about pain and heartache, but takes his message from the veins and speaks his lesson from the brain, seeing the beauty through the pain. The chorus repeats how pain made him a believer, and how it broke him down but built him up again. He ends with a shoutout to the fire and the flames, and how the person he's singing to is the face of the future and the blood in his veins. In short, pain is the ultimate motivator for this guy, and now he's a believer because of it. Maybe we should all try embracing our pain and see where it takes us. Or, you know, we could just take some Advil and call it a day. Your call.
