That ratio would be demoralizing if it happened steadily, but—for me, anyway—it tends to reflect long fallow periods where I'm sort of bumbling about in the dark trying to get a handle on anything, and then streaks where I know exactly what I want to do and the clarity of purpose shapes the songs. Looking back at the notebook from 2013–2014, there's a stretch of nascent ideas, and then, in immediate succession, "Everything I Think I Know Is Wrong," "Sleepwalker," "This Is Where I Get Off" (which never got past the demo, which is fine), and "<3." "Like" is a few pages after that.
Unfortunately you don't get to the streaks without bumbling about first. Or I don't, at least.
