Falling in love is awesome, but I'm never drawn to happy songs per se, so whenever you sit down to write a heartbreak song and you're happily in love, it's like, 'OK, now I have to go back to a sad place to get something good.'
And one thing that I always believed and that I knew for certain was that I could never have sustained a personal relationship while I worked this hard, or while I was that driven this intensely by the story.
