Managing Oneself

IDEA 1
People must manage their own careers
Drucker argues that in a knowledge economy, people can no longer rely on companies to manage their careers. Each person must take responsibility for developing themselves and finding where they can contribute most.
IDEA 2
Know your strengths
Drucker suggests feedback analysis: write down expected results of decisions and compare them later with what happened. This reveals strengths. Over time, you see which kinds of work you do well and which you do badly.
IDEA 3
Know how you perform
Drucker asks whether you are a reader or a listener, whether you work best alone or with others. Understanding this improves performance. Working in a way that suits you is often easier than trying to copy someone else's style.

IDEA 1
Effectiveness is a learnable habit
Drucker argues that being effective, meaning getting the right things done, is not an inborn gift. It is a set of practices anyone in a decision-making role can learn. He defines an executive as any knowledge worker responsible for contributing results.
IDEA 2
Know where your time goes
Drucker says time is the scarcest resource, and most people misjudge how they spend it. He recommends keeping a time log, then cutting activities that need not be done at all and handing others to people who can do them.
IDEA 3
Consolidate time into large blocks
Important work, such as thinking or building relationships, needs long uninterrupted stretches. Scattered fifteen-minute slots are almost useless, Drucker argues, so effective people gather their free time into big blocks and guard them.

IDEA 1
Management became a discipline
Drucker's book helped establish management as a distinct field of study and practice. He argues that managers are essential to modern society, because organisations depend on them to turn resources into results.
IDEA 2
Ask what your business is
Drucker argues that every business must ask what its business is, who its customers are and what they value. These questions guide strategy. A company that cannot answer them clearly is likely to drift without direction.
IDEA 3
Customers define the business
Drucker argues that the purpose of a business is to create a customer. What customers buy determines what the business is. A business does not exist for its owner's pride but because someone is willing to pay for what it offers.
