Tao Te Ching

That which is at rest is easily kept hold of; before a thing has given indications of its presence, it is easy to take measures against it; that which is brittle is easily broken; that which is very small is easily dispersed.

Action should be taken before a thing has made its appearance; order should be secured before disorder has begun. The tree which fills the arms grew from the tiniest sprout; the tower of nine storeys rose from a (small) heap of earth; the journey of a thousand li commenced with a single step.
