Spare at the brim, not at the bottom. [ Proverb ]

Faster and more fast,
O'er night's brim, day boils at last;
Boils, pure gold, over the cloud-cup's brim. [ Robert Browning ]

Life's enchanted cup but sparkles near the brim. [ Byron ]

Years steal
Fire from the mind, as vigour from the limb;
And life's enchanted cup but sparkles near the brim. [ Byron ]

The heart that is to be filled to the brim with holy joy must be held still. [ Bovee ]

If you cannot inspire a woman with love of you, fill her above the brim with love of herself: all that runs over will be yours. [ Colton ]
