Hope is the struggle of the soul, breaking loose from what is perishable, and attesting her eternity.
— Herman Melville

Time is at once the most valuable and the most perishable of all our possessions.
John Randolph perishables quote

One cannot buy, rent or hire more time. The supply of time is totally inelastic. No matter how high the demand, the supply will not go up. There is no price for it. Time is totally perishable and cannot be stored. Yesterday's time is gone forever, and will never come back. Time is always in short supply. There is no substitute for time. Everything requires time. All work takes place in, and uses up time. Yet most people take for granted this unique, irreplaceable and necessary resource.
— Peter Drucker

Youth itself is a talent -- a perishable talent.
— Eric Hoffer

Architecture worth great attention. As we double our numbers every 20 years we must double our houses. Besides we build of such perishable materials that one half of our houses must be rebuilt in every space of 20 years. So that in that term, houses are to be built for three fourths of our inhabitants. It is then among the most important arts: and it is desireable to introduce taste into an art which shews so much.
— perishables quotation by Thomas Jefferson
