That which is everybody’s business is nobody’s business.

Responsibility that is shared evenly across a group tends to evaporate. Each person assumes someone else has it, nobody feels the weight of it, and the task sits there while everyone remains individually blameless. It is not laziness so much as arithmetic: attention follows ownership, and unowned work has nothing to pull it forward.

Find the thing in your household or team that everyone agrees matters and nobody has been doing. Put one name against it, with a date, even if the name is yours, and notice how quickly it starts to move.
