There aren’t that many words used in everyday language that start with the letter “X,” even though alone, it can be used from everything from signing your name to marking a place. I went through xenomorphic and xenophobic. XXX, X Chromosome, and X-ray. I went with X marks the spot because quests feature prominently in lots of fiction. We don’t always say “X marks the spot,” but it’s implied.
I love quest fiction. I love the idea of someone searching for anything, whether it’s treasure, meaning, a lost person, or true love. I think that most of us are searching for one or all of these things, but fiction makes the quest easily identifiable.
When people talk about quest fiction, I think they’re usually referring to fantasy novels like The Hobbit and Lord of the Rings, instead of questing in a broader sense. However if most of us drew a map of our own lives, we’d probably be able to identify our own personal “X.” What are you searching for?

I did “X Marks The Spot” too.
