The word enough changes meaning without changing quantity when another person joins the table.

Sufficiency is a relationship, not an amount. Nothing about the food changed when another person sat down, and enough became not enough, which reveals that the word was always describing a fit between quantity and circumstance. The same is true of time, money, and patience.

Which means enough can sometimes be reached by changing the circumstance rather than the amount. Fewer commitments rather than more hours. A smaller set of things you are trying to do well. Before working to increase the quantity, it is worth asking who or what has recently joined the table.
