What does "Whatever It Takes" by Imagine Dragons mean?

We're moments away (at the time of the writing of this) from Imagine Dragons dropping Evolve and the seven songs from them that we haven't heard yet. While waiting, I realized I hadn't blogged about "Whatever It Takes" yet, so I decided I'd better give it a shot. I've already blogged about it and made a video explaining it, but it's time to get serious and to explain it line-by-line.
