Time is a resource whose supply is inversely proportional to its demand.

In the big picture, the whole world at every level, micro, macro, physiological, psychological, material, economical, spiritual, all are a demand-supply problem.

Demand continues to rise against a backdrop of stagnant supply. It's going to be a very interesting summer.

The demand is far, far exceeding the supply.
