Then it began to dawn on us: There was no miracle moment. Although it may have looked like a single-stroke breakthrough to those peering in from the outside, it was anything but that to people experiencing transformation from within. Rather, it was a quiet, deliberate process of figuring out what needed to be done to create the best future results and then simply taking those steps, one after the other, turn by turn of the flywheel. After pushing on that flywheel in a consistent direction over an extended period of time, they'd inevitably hit a point of breakthrough.
