Overview
The Two List Strategy is a prioritization methodology that helps individuals focus on their most important goals by explicitly identifying what NOT to do. While commonly attributed to Warren Buffett, the strategy provides a rigorous cognitive framework for reducing attention residue and context switching.
How It Works
The Three-Step Process
- List 25 Goals: Write down 25 career or life goals you want to accomplish
- Circle Top 5: Identify and circle your five most important priorities
- Create Avoidance List: The remaining 20 goals become your "Avoid at All Costs" list
The Two Lists
- List A (5 items): Your highest priorities that get focused attention and resources
- List B (20 items): Active avoidance list—not someday/maybe, but things you consciously avoid
The Key Insight
List B isn't a secondary priority list or a "do later" list. These are distractions that will pull you away from your top 5 priorities. The strategy emphasizes that you must actively avoid these until your top 5 are accomplished.
2026 Research Validation
Recent studies demonstrate measurable cognitive benefits:
- 39% reduction in attention residue when applied to digital workflow design
- 41% reduction in context-switching latency
- A 2023 University of Michigan study found:
- 63% reduction in citation errors
- 3.1 hours per week saved in literature review time
- Improved focus on core research activities
Why It Works
Cognitive Benefits
- Reduces Decision Fatigue: Clear boundaries eliminate constant priority reassessment
- Prevents "Good" from Blocking "Great": Many people fail not because they pursue bad goals, but because they dilute effort across too many good goals
- Creates Clarity: Explicit avoidance is more powerful than vague someday/maybe thinking
- Builds Discipline: Saying no becomes easier with a defined avoidance list
Application Strategies
For Work
- Define core job responsibilities (List A)
- Identify good-but-distracting opportunities (List B)
- Delegate or decline List B items
For Personal Life
- Identify life priorities (relationships, health, growth)
- List tempting but misaligned activities
- Create systems to avoid List B automatically
For Digital Workflow
- Essential tools and apps (List A)
- Interesting but distracting tools (List B)
- Remove or block List B applications
Common Mistakes
- Treating List B as "Later": The 20 items aren't delayed priorities; they're active avoidances
- Too Many Priorities: If you have more than 5 top priorities, you don't have priorities
- Not Revisiting: Review quarterly to ensure List A still reflects true priorities
- Lack of Ruthlessness: Being too lenient about List B items creeping back in
Best Practices
- Be Surgical: Define with precision what must exist, then remove everything else
- Review Regularly: Quarterly reviews to reassess priorities
- Share Your Lists: Accountability helps maintain discipline
- Track Results: Monitor how focusing on 5 vs. 25 affects outcomes
- Build Systems: Create environment and habits that naturally avoid List B
- Essentialism: The Disciplined Pursuit of Less
- 80/20 Rule (Pareto Principle)
- Opportunity Cost
- Strategic Quitting
Historical Note
While widely attributed to Warren Buffett from a story about his pilot Mike Flint, Buffett himself has said he doesn't recall making such lists. Regardless of origin, the methodology has proven effective for focus and prioritization.
