How Does Waste Take Root?
We find solutions to conditions and then forget to change
the solutions when the conditions change, e.g. stopgap
solutions
Over time, when conditions change, we no longer
remember why we do certain things or what problem they
were intended to solve
Hence it is important to ask why, over and over again,
about everything we do. Only in this way will waste fail to
take root.
