"He Pushes the First Domino"

All my doubts and uncertainties lined up in my mind like endless dominoes. I didn't know where to start. Vivaldi's help was a small push on the very first domino. After that, everything began to fall on its own. One doubt fell, knocking down the next, creating a clear path to understanding. He didn't need to knock everything down for me; he just needed to show me where to start.
