Not a Taoist, but there is Truth here....

Eleven

Thirty spokes share the wheel's hub;
It is the center hole that makes it useful.

Shape clay into a vessel;
It is the space that makes it useful.

Cut doors and windows for a room;
It is the holes which make it useful.

Therefore profit comes from what is there;
Usefulness from what is not there.

--Lao Tzu, The Tao Te Ching
