1. “What’s the ONE Thing I can do such that by doing it everything else will be easier or unnecessary?”
This is the core question of the book. It encourages you to focus on the single most important task or action that has the biggest impact. By doing this ONE thing, other tasks either become easier to handle or aren’t needed at all.

2. “Success is about doing the right thing, not about doing everything right.”
You don’t need to be perfect or do every little task to succeed. What matters is identifying and focusing on the most important actions that will move you toward your goals.

3. “If you chase two rabbits, you will not catch either one.”
Trying to do too many things at once leads to failure or poor results. To be successful, you must focus on one goal or task at a time rather than spreading your attention too thin.

4. “Extraordinary results are directly determined by how narrow you can make your focus.”
The more you narrow down your focus to the most critical tasks, the more likely you are to achieve extraordinary success. It emphasises depth of effort on one thing rather than a shallow effort on many things.

5. “Multitasking is merely the opportunity to screw up more than one thing at a time.”
Multitasking is inefficient and often leads to mistakes. It’s better to focus on one task at a time and do it well, rather than juggling multiple tasks and compromising quality or results.
