    About this tool

    Overview

    The 90-90-1 rule was developed by leadership expert and business coach Robin Sharma, best known as the author of bestsellers such as "The Monk Who Sold His Ferrari" and "The 5AM Club." This productivity technique emphasizes focusing on your most important goal during your peak morning hours.

    How It Works

    For the next 90 days, devote the first 90 minutes of your work day to the one best opportunity in your life. The most valuable hours of the day should be invested in the most important project rather than wasted on time-wasters or routine tasks.

    The Three Numbers Explained

    90 Days

    90 days is not too long or too short, providing a manageable timeframe to build habits without feeling overwhelming. This duration allows for:

    • Meaningful progress on significant goals
    • Habit formation and reinforcement
    • Visible results that build momentum
    • A focused sprint toward a specific outcome

    90 Minutes

    Scientific studies show that we can hardly concentrate on one thing for longer than 90 minutes without needing a break. This timeframe is:

    • Tied to the ultradian rhythm (cycle present in sleeping and waking lives)
    • The limit for focusing intensely on any given task before losing steam
    • Long enough for deep work
    • Short enough to maintain peak focus

    1 Opportunity

    Focus on your single "game-changing move" - the most important goal or project that will have the biggest impact on your success.

    Why These Times Matter

    The first hours of the day are too valuable to waste on time-wasters or routine tasks. Morning hours typically represent:

    • Peak mental clarity
    • Highest willpower reserves
    • Fewest distractions
    • Best conditions for deep, focused work

    Benefits

    • Peak Performance: Leverages your best hours for most important work
    • Habit Formation: 90 days is sufficient to establish lasting habits
    • Deep Focus: 90 minutes allows for meaningful deep work sessions
    • Priority Clarity: Forces identification of truly important work
    • Momentum Building: Daily progress creates compounding results

    Implementation Tips

    1. Identify your one game-changing opportunity or project
    2. Block the first 90 minutes of your workday (no meetings, no interruptions)
    3. Start immediately each morning - no email, no social media first
    4. Commit to the full 90 days to establish the habit
    5. Protect this time fiercely from distractions

    Ideal For

    • Entrepreneurs building businesses
    • Professionals working on career-defining projects
    • Creatives developing major works
    • Anyone with a significant goal requiring sustained effort
    • People who struggle with prioritization

    Scientific Basis

    The 90-minute focus period aligns with research on ultradian rhythms, which are natural cycles of energy and focus that occur throughout the day. Working in harmony with these biological rhythms enhances productivity and reduces burnout.
