10/90 Rule of Time Management

Overview

The 10/90 Rule, taught by Brian Tracy in "Eat That Frog!", states that spending the first 10% of your time planning and organizing your work before you begin will save you as much as 90% of the time in getting the job done once you get started.

The Mathematics

For a 10-hour project:

• Spend 1 hour (10%) planning
• Save 9 hours (90%) in execution time
• Complete more effectively in less total time

Why It Works

Clarity: Planning clarifies exactly what needs to be done

Direction: Eliminates false starts and wasted motion

Efficiency: Identifies the most effective approach before committing

Resource Optimization: Ensures you have what you need before starting

Application

Before Any Project:

1. Define the desired outcome clearly
2. List all steps required
3. Identify resources needed
4. Anticipate obstacles
5. Determine best sequence of actions
6. Allocate time for each step

Before Each Day:

• Plan tomorrow tonight
• List all tasks
• Prioritize using ABCDE method
• Estimate time requirements
• Schedule most important tasks first

Common Mistakes

• Skipping planning to "save time"
• Rushing into execution prematurely
• Planning too much (analysis paralysis)
• Not reviewing and adjusting plans

Benefits

• Fewer mistakes and revisions
• Less time wasted on wrong approaches
• Better results with less stress
• Improved ability to estimate time
• Greater sense of control
