Every memorable character has a little something extra: a twitch of the eye, a fondness for obscure quotes, a habit of collecting something unusual. These character quirks can make fictional people feel real, lived-in, and compelling.

Not every character needs a quirk but even one well-placed detail can say more than a paragraph of exposition. When writing, choose quirks that reveal something deeper: a quirk that comes from childhood, trauma, love, or belief. Let it evolve. Let it be challenged.
And above all: have fun with it. These little oddities are where characters come alive.
