“There is nothing so useless as doing efficiently that which should not be done at all.” — Peter Drucker
Peter Drucker was a leader in management philosophy and effectiveness.
As a writer, management consultant, and social ecologist, he played an influential role in shaping key concepts around business, innovation, decision making, leadership, productivity, time management, and personal effectiveness.
He first coined the term “knowledge worker” back in 1959, and helped pioneer knowledge work productivity.
Peter Drucker Challenged the Status Quo
I originally stumbled across Drucker while I was studying effective decision making techniques and I found that he was a wealth of insight in many other areas.
Drucker had a crisp way of making his points and he challenged the status quo.
I think what I liked most about Drucker was his ability to articulate things that you know to be true. While I never got to meet Drucker, I get to study his legacy in the form of several books and great quotes.
This post is a walkthrough of the lessons I’ve learned as well as my favorite Drucker quotes.
