Business Personal Development Management

Managing Oneself (Summary)

by Peter F. Drucker

Why do so many smart, ambitious people fail to achieve their goals? They spend their careers trying to fix their weaknesses. Peter Drucker argues this is a tragic waste of time. The secret to a life of contribution isn't becoming a well-rounded person, but becoming a sharp, one-sided tool and finding exactly where you're meant to cut.

Stop Fixing Your Weaknesses

The path to excellence is through amplifying what you're already good at, not through marginally improving your weaknesses. True competence can only be built on a foundation of strength, so focus your energy there and manage your weaknesses so they don't get in the way.

Drucker gives the example of a brilliant financial analyst who is terrible at managing people. Instead of forcing him into a management role he's ill-suited for, the company makes him a senior individual expert. This allows his analytical strength to shine without being sabotaged by his managerial weakness.

Are You a Reader or a Listener?

Your performance is dictated by your innate working style. Knowing whether you best process information by reading detailed reports or by listening to verbal briefings is as crucial as knowing your strengths. Working against your nature is a recipe for failure.

President Dwight D. Eisenhower was a classic "reader." His press conferences were famously rambling because he needed to absorb information from written briefs first. In contrast, President Lyndon B. Johnson was a "listener" who thrived on live, verbal briefings. Placing either in the wrong information environment would have crippled their effectiveness.

Pass the 'Mirror Test'

Your values are your ultimate non-negotiables. Working in a role or for an organization that conflicts with your fundamental values will lead to frustration and poor performance, no matter how skilled you are or how much you're paid.

A top executive was offered a fantastic promotion at another company. He turned it down because the new company's culture was to "promote from within" only in emergencies. His own value system dictated that a company's first duty is to its own people, and he couldn't see the kind of person he wanted to be in the "mirror" if he worked there.

Plan Your Second Half

With lifespans increasing, a single career is no longer enough. You must start developing a second major interest or a parallel career long before your primary one ends to maintain your engagement, contribution, and purpose in life.

A successful business executive who always loved history began volunteering to teach at a local college on weekends. When she eventually retired from her corporate job, she already had a fully developed, fulfilling second career waiting for her, preventing the common "what now?" crisis of retirement.
