Every bird must hatch her own egg.

A person should take responsibility for a matter that is theirs instead of expecting someone else to carry it through for them.

The image of hatching an egg stresses the attention required to bring something of one’s own to completion. Others may help, but the primary responsibility remains with the person concerned.

Use it when someone is leaving a personal duty or undertaking to others. It can serve as a reminder to take an active part in work whose outcome chiefly concerns oneself.
