The skill of a pilot is in bringing vertical speed to zero just at the landing point.

The skill of a bell ringer is in bringing rotational speed to zero just at the balance point.

The skill of managing change is in making the rate of change as close to zero as possible at the point of change.

Successful pilots, bell ringers and change managers do this apparently effortlessly by preparing their trajectory well ahead of time and being continually alert to changes in the environment which might require a correction – but those corrections will tend to be small in relation to the goal.

Unsuccessful pilots and bell ringers crash.
