The usual selection of quote that have inspired or amused me this week.

Thirty spokes unite at the hub
but the ultimate use of the wheel depends on the part where nothing exists.
Clay is molded into a vessel
but the ultimate use of the vessel depends upon the part where nothing exists.
Doors and windows are cut out of the walls of a house
but the ultimate use of the house depends upon the parts where nothing exists.
So, there is advantage in using what can be seen, what exists.
And there is also advantage in using what cannot be seen, what is non-existent.
[Lao Tzu, Tao Te Ching, Chapter 11]

There are intelligent people and thick people. There are energetic people and lazy people. By far the most dangerous is the energetic but thick person.
