“The enemy’s gate is down” is a quote that always helps me wrap my head around a tough problem. Orson Scott Card wrote the Ender’s Game series, where you’ll find the quote, and in the story, the protagonist is the team leader in what amounts to a zero-gravity game of laser tag. Now, even in zero-gravity, you might want to keep your orientation about you. Left is still left, right is still right. But the protagonist realizes that by simply spinning in midair and orientating himself and his team so that the enemy team is BELOW them, they automatically have the high ground. So, to me, “the enemy’s gate is down” reminds me that you can REFRAME a problem any way you like. You’re not bound by conventions in the creative world, and even if everyone else is doing it one way, they might be doing it wrong! The corollary to this quote is “If they give you ruled paper, write the other way.” Don’t take any of the conventions you’re taught for fact.
