Peter F. Drucker

In all recorded history there has not been one economist who has had to worry about where the next meal would come from.

Here I am, fifty-eight, and I still don't know what I want to be when I grow up.

There is nothing so useless as doing efficiently that which should not be done at all.

Don't put the fate of your business in the delusions of economists.

The most important thing in communication is to hear what isn't being said.

Quality in a product or service is not what the supplier puts in. It is what the customer gets out and is willing to pay for. A product is not quality because it is hard to make and costs a lot of money, as manufacturers typically believe. This is incompetence. Customers pay only for what is of use to them and gives them value. Nothing else constitutes quality.

Zarządzanie to sztuka robienia rzeczy właściwie. Przywództwo to robienie właściwych rzeczy

Management is doing things right; leadership is doing the right things.
