Quick Reference

Deep Work

A state of distraction-free concentration where you push your cognitive capabilities to their limit. Coined by Cal Newport, deep work produces results that are difficult to replicate and creates outsized value in the knowledge economy.

Time Blocking

A scheduling method where you divide your day into discrete blocks of time, each assigned to a specific task or category of work. This approach combats reactive work habits and ensures important tasks receive dedicated attention.

The Eisenhower Matrix

A prioritization framework that categorizes tasks into four quadrants based on urgency and importance: urgent and important (do first), important but not urgent (schedule), urgent but not important (delegate), and neither urgent nor important (eliminate).

Getting Things Done (GTD)

A productivity methodology created by David Allen based on capturing all tasks and ideas into an external system, clarifying their next actions, organizing them by context, reviewing regularly, and engaging with confidence. The core principle is that the mind is for having ideas, not holding them.

Pareto Principle (80/20 Rule)

The observation that roughly 80% of results come from 20% of efforts. In productivity, this principle is used to identify and focus on the vital few activities that generate the most significant outcomes rather than spreading effort across the trivial many.

Pomodoro Technique

A time management method developed by Francesco Cirillo that breaks work into 25-minute focused intervals (pomodoros) separated by 5-minute breaks, with a longer 15-30 minute break after every four pomodoros. The technique leverages timeboxing and regular recovery to sustain focus.

Decision Fatigue

The deterioration of decision-making quality after making a long series of decisions. As willpower and cognitive resources deplete throughout the day, people tend to make poorer choices, procrastinate, or default to the easiest option.

Batching

The practice of grouping similar tasks together and completing them in a single dedicated session rather than scattering them throughout the day. Batching reduces the cognitive cost of context switching and allows you to build momentum within a task type.

Parkinson's Law

The adage that work expands to fill the time available for its completion. By setting tighter deadlines and constraining the time allotted for tasks, you can often complete work faster without sacrificing quality.

Flow State

A mental state of optimal performance identified by psychologist Mihaly Csikszentmihalyi, characterized by complete immersion in an activity, loss of self-consciousness, and distorted sense of time. Flow occurs when the challenge level closely matches skill level.
