Love, and do what you will. If you keep silence, do it out of love. If you cry out, do it out of love. If you refrain from punishing, do it out of love.
I'm not the kind of guy who walks around with a notebook writing lyrics. For me, melody and song structure come first and foremost. Unless the melody gets stuck in my head, I'll move on. Once I have the musical idea pretty firm, I just try to write words that are incredibly honest and relate to my life on that given night. I'll sit with the music on my headphones and pen and paper all night long until it's done.
