The “Rule of 9” That Helped Build a Billion-Dollar Company

Hey, Arjun here.

She started a dating app called Bumble in 2014 that let women make the first move and became the youngest self-made billionaire in the world. Nearly 9 years and countless Bumble weddings and babies later, she’s celebrated over 1.5 billion first moves.

Meet Whitney Wolfe Herd.

The 2-Minute Hack: The Rule of 9

Whitney Wolfe Herd uses a powerful decision-making framework I call “The Rule of 9″ to filter what deserves her attention:

๐˜ ๐˜ณ๐˜ฆ๐˜ข๐˜ญ๐˜ญ๐˜บ ๐˜ต๐˜ณ๐˜บ ๐˜ต๐˜ฐ ๐˜ข๐˜ด๐˜ฌ ๐˜ฎ๐˜บ๐˜ด๐˜ฆ๐˜ญ๐˜ง ๐˜ต๐˜ฉ๐˜ฆ ๐˜ฒ๐˜ถ๐˜ฆ๐˜ด๐˜ต๐˜ช๐˜ฐ๐˜ฏ ๐˜ฐ๐˜ง ๐˜ฏ๐˜ช๐˜ฏ๐˜ฆ. ๐˜ž๐˜ช๐˜ญ๐˜ญ ๐˜ต๐˜ฉ๐˜ช๐˜ด ๐˜ฎ๐˜ข๐˜ต๐˜ต๐˜ฆ๐˜ณ ๐˜ช๐˜ฏ ๐˜ฏ๐˜ช๐˜ฏ๐˜ฆ ๐˜ฎ๐˜ช๐˜ฏ๐˜ถ๐˜ต๐˜ฆ๐˜ด, ๐˜ฏ๐˜ช๐˜ฏ๐˜ฆ ๐˜ฉ๐˜ฐ๐˜ถ๐˜ณ๐˜ด, ๐˜ฏ๐˜ช๐˜ฏ๐˜ฆ ๐˜ฅ๐˜ข๐˜บ๐˜ด, ๐˜ฏ๐˜ช๐˜ฏ๐˜ฆ ๐˜ธ๐˜ฆ๐˜ฆ๐˜ฌ๐˜ด, ๐˜ฏ๐˜ช๐˜ฏ๐˜ฆ ๐˜ฎ๐˜ฐ๐˜ฏ๐˜ต๐˜ฉ๐˜ด ๐˜ฐ๐˜ณ ๐˜ฏ๐˜ช๐˜ฏ๐˜ฆ ๐˜บ๐˜ฆ๐˜ข๐˜ณ๐˜ด? ๐˜๐˜ง ๐˜ช๐˜ต ๐˜ธ๐˜ช๐˜ญ๐˜ญ ๐˜ต๐˜ณ๐˜ถ๐˜ญ๐˜บ ๐˜ฎ๐˜ข๐˜ต๐˜ต๐˜ฆ๐˜ณ ๐˜ง๐˜ฐ๐˜ณ ๐˜ข๐˜ญ๐˜ญ ๐˜ฐ๐˜ง ๐˜ต๐˜ฉ๐˜ฐ๐˜ด๐˜ฆ, ๐˜ฑ๐˜ข๐˜บ ๐˜ข๐˜ต๐˜ต๐˜ฆ๐˜ฏ๐˜ต๐˜ช๐˜ฐ๐˜ฏ ๐˜ต๐˜ฐ ๐˜ช๐˜ต.

Why This Works:

This simple framework creates a powerful time perspective that:

  • Instantly filters out short-term distractions
  • Identifies what truly deserves your focus
  • Prevents reactionary decision-making
  • Creates mental space for long-term thinking
  • Reduces stress about things that won’t matter long-term

How to Implement the Rule of 9

1. When faced with a decision or problem, ask yourself if it will matter in 9 minutes

2. If yes, ask if it will matter in 9 hours

3. Continue through each timeframe: 9 days, 9 weeks, 9 months, 9 years

4. Only dedicate significant energy to issues that will matter across multiple timeframes

5. For issues that only matter in shorter timeframes, find quick solutions or delegate

The magic happens when you realize how few things actually pass the full 9-year test. This creates extraordinary clarity about what deserves your limited time and attention.
