There’s always that moment when you realize what it’s going to be. You might have an overarching theme and you need to fill in the blanks—and then there’s this ‘aha’ moment when you see where it’s going. That’s the most satisfying part of writing.

—Rosanne Cash

Write about the last time you had an ‘aha’ moment while you were writing.

How did it manifest itself? How are you setting the stage for the next one?
