## When to use it

Discuss a tendency for excess to produce the opposite effect.

It is a general observation, not a guaranteed natural law.

## The image & its use

The expression pictures a movement reaching its furthest point and then turning back. It often warns that too much of a useful thing can become unhelpful. Excessive decoration may reduce clarity, or constant changes may make a plan harder to follow. The phrase invites moderation and attention to changing conditions. Explain the mechanism behind the reversal where possible; simply announcing that an extreme must reverse does not establish when or how it will happen.
