- Goal Sprint
- A defined time window β typically 30 to 90 days β during which all discretionary effort is concentrated on a single significant objective.
- Opportunity Cost
- The value of the best alternative foregone when you choose to spend time or energy on a lower-priority activity.
- Cognitive Load
- The total amount of mental effort actively used in working memory at any given time; excessive load slows decision-making and reduces output quality.
- Parkinson's Law
- The observation that work expands to fill the time available for its completion β used here to explain why unconstrained schedules breed low-value activity.
- Deep Work
- Cognitively demanding, distraction-free work that pushes your abilities and creates significant value β contrasted with shallow, reactive tasks.
- Reactive Mode
- A work pattern driven by incoming demands β notifications, requests, and interruptions β rather than proactive execution of planned priorities.
- Comparison Trap
- The habit of measuring your progress against others' visible outputs, which consistently distorts self-assessment and redirects attention from your own path.
- Perfectionistic Delay
- Postponing execution because conditions, information, or preparation do not yet feel sufficient β a recognized pattern that delays progress without improving outcomes.
- Energy Management
- The deliberate allocation of physical and mental energy to tasks according to their priority β distinct from time management, which tracks hours not quality of focus.
- Scope Creep (personal)
- The gradual addition of commitments, favors, and side projects that expand personal workload beyond what serves the primary goal.
