The empty center is the useful part of a bowl.

Function often lives in what is absent. Clay makes a bowl possible, but the part that holds soup is the space, and no amount of admiring the walls changes which part is doing the work. The same shape appears elsewhere: the pause that makes speech intelligible, the gap in a diary that makes the week workable, the silence that lets another person answer. Substance gets the credit; emptiness does the job.

Look for the hollow in something you are making or living inside this week. If it has been filled in, consider what would be gained by opening it back up.
