Two List Strategy

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

1. List 25 Goals: Write down 25 career or life goals you want to accomplish
2. Circle Top 5: Identify and circle your five most important priorities
3. 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

1. Reduces Decision Fatigue: Clear boundaries eliminate constant priority reassessment
2. Prevents "Good" from Blocking "Great": Many people fail not because they pursue bad goals, but because they dilute effort across too many good goals
3. Creates Clarity: Explicit avoidance is more powerful than vague someday/maybe thinking
4. 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

1. Treating List B as "Later": The 20 items aren't delayed priorities; they're active avoidances
2. Too Many Priorities: If you have more than 5 top priorities, you don't have priorities
3. Not Revisiting: Review quarterly to ensure List A still reflects true priorities
4. 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

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.
