Why It Works
The Domino Effect
Success is sequential, not simultaneous. Like dominoes:
- Each success makes the next one easier
- Small actions can topple much bigger results
- Focus on the lead domino, not all of them
The 80/20 Principle on Steroids
- 20% of efforts create 80% of results
- Within that 20%, there's one thing that matters most
- Finding that ONE Thing multiplies your effectiveness

Common Mistakes
Asking Wrong Questions
Instead of: "What are all the things I need to do?" Ask: "What's the ONE Thing?"
Instead of: "How can I do everything?" Ask: "What can I do such that everything else becomes easier or unnecessary?"
Not Going Small Enough
If your answer feels overwhelming:
- Make it smaller
- Make it more specific
- Focus on the very next action
The Six Lies This Exposes
- Everything matters equally - It doesn't
- Multitasking works - It doesn't
- A disciplined life - Habits beat willpower
- Willpower is always on will-call - It's finite
- A balanced life - Success requires imbalance
- Big is bad - Thinking big is essential
Integration with Time Management
Daily Planning
- Ask the question each morning
- Identify your ONE Thing for the day
- Time block it first, before anything else
- Protect that time fiercely
- Everything else is secondary
Weekly Planning
- Identify ONE Thing for the week
- Break into daily ONE Things
- Schedule them in advance
- Review and adjust
Goal Setting
- Start with lifetime goal ONE Thing
- Work backward: 5 years, 1 year, month, week, day
- Create connected chain of dominos
- Focus on the very next one
Power of Sequential Success
Rather than trying to do everything at once:
- Identify the first domino
- Focus exclusively on it
- Complete it fully
- Move to the next one
- Repeat
Each success builds momentum for the next.
