Nothing in the world
is as weak as water.
Yet for dissolving granite mountains
nothing can surpass it.
The soft overcomes the hard;
the easy overcomes the difficult.
Everyone knows this is true,
but few can put it into practice.
Therefore the Master Seller
Remains cool under fire.
Prepared they are ready for all objections.
Because they have stopped avoiding work
their work gets done.
See the world as it is
Focus on the hard
until the hard becomes easy.
The Tao Te Ching of Sales
