Overview
The Law of Three (also called Rule of Three) is a productivity principle popularized by Brian Tracy that states only three tasks and activities account for 90% of the value of the contribution you make to your business, no matter how many different things you do.
How It Works
The rule is simple:
- Write down three things you want to accomplish today
- Write down three things you want to accomplish this week
- Write down three things you want to achieve this year
Core Philosophy
The Law of Three forces you to identify what truly moves the needle in your work and life. It removes the guesswork - you already know your priorities. Most importantly, it acts as a forcing function, compelling you to be ruthless about what you focus on since you can only choose three main priorities for each timeframe.
Key Benefits
- Clarity: Eliminates confusion about what matters most
- Focus: Concentrates effort on high-value activities
- Simplicity: Easy to remember and implement
- Scalability: Works across different time horizons
- Productivity: 90% of value from just three activities
- Decision-making: Clear framework for saying no
Implementation Steps
- Daily Three: Every morning, identify the three most important tasks that will create the most value today
- Weekly Three: At the start of each week, determine the three key outcomes that will make the week successful
- Yearly Three: At the beginning of the year, set three major goals that align with your long-term vision
Comparison with Similar Methods
vs. 1-3-5 Rule: The 1-3-5 rule (one big task, three medium, five small) focuses on daily task volume, while the Law of Three emphasizes impact across multiple timeframes.
vs. MIT Method: Most Important Tasks (MIT) typically identifies 2-3 daily priorities, similar to the daily aspect of the Law of Three, but without the weekly/yearly framework.
vs. Warren Buffett's 5/25: Buffett's method uses 25 goals narrowed to 5, while the Law of Three is more restrictive with just 3 priorities.
Common Challenges
- Too many priorities: Resisting the urge to add "just one more" task
- Changing priorities: Staying committed to the three even when new opportunities arise
- Urgent vs. important: Not letting urgent tasks replace important ones
Best Practices
- Review and reaffirm your three priorities regularly
- Align daily priorities with weekly and yearly goals
- Block calendar time for your three priorities first
- Say no to activities outside your three focuses
- Evaluate activities against contribution to your three goals
Real-World Application
In business, your three daily tasks might be: close a major sale, hire a key team member, and finalize product strategy. Your three weekly goals could be: increase revenue by 10%, complete team restructuring, and ship product update. Your three yearly objectives might be: double company revenue, expand to new market, and build world-class team.
