Peter Drucker Yesterday Quotations

The greatest danger in times of turbulence is not the turbulence; it is to act with yesterday's logic.

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.

Innovation requires us to systematically identify changes that have already occurred in a business - in demographics, in values, in technology or science - and then to look at them as opportunities. It also requires something that is most difficult for existing companies to do: to abandon rather than defend yesterday.

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 economic activity is by definition "high risk." And defending yesterday--that is, not innovating--is far more risky than making tomorrow.

Defending yesterday is far more risky than making tomorrow.

It is more productive to convert an opportunity into results than to solve a problem - which only restores the equilibrium of yesterday.

Unless strategy evaluation is performed seriously and systematically, and unless strategists are willing to act on the results, energy will be used up defending yesterday.

The honest work of yesterday has lost its social status, its social esteem.
