The 7 Habits of Highly Effective People

Stephen R. Covey · 1989

Covey grounds effectiveness in character and principles rather than quick-fix techniques. The habits move outward: first master yourself (be proactive, begin with the end in mind, put first things first), then work well with others, then renew yourself.

Its most quoted contribution is the time-management matrix — sorting work by urgency and importance — and the argument that a good life comes from spending more time on what's important but not urgent, before it becomes a crisis.
