Fear not the loss of the bell more than the loss of the steeple.

The proverb warns against giving a lesser loss more attention than a larger, more consequential one.

It calls for a sense of proportion: concern for one part should not eclipse the danger facing the greater whole.

Use it when someone is preoccupied with a relatively small setback while a more serious loss is at stake. It can redirect attention from one valued part to the greater whole.
