Opportunities are like sunrises. If you wait too long, you miss them
We put thirty spokes to make a wheel; but it is on the hole in the centre that the use of the cart hinges.
We make a vessel from a lump of clay; but it is the empty space within the vessel that makes it useful.
We make doors and windows for a room; but it is the empty spaces that make the room liveable.
Thus, while existence has advantages, it is the emptiness that makes it useful
(Lao Tzu c.604 - 531 B.C.)
