The Math Behind The 5-Hour Rule: Why You Need To Learn 1 Hour Per Day Just To Stay Relevant
Outdated knowledge
The rate at which knowledge is becoming outdated is predictable and growing exponentially. For example:
- Two surgeons found that half of the facts in surgery become false every 45 years.
- In the 1980s, bacon, butter, and eggs were three of the worst foods you could eat for your heart. Now, many argue they are healthy.
- Artificial intelligence, app development, social media management, YouTube content creation, and online course creation barely existed fifteen years ago.
- Entrepreneurship classes taught to spend hundreds of hours creating in-depth, heavily researched business plans. Now, they are taught NOT to do business plans, but to focus on talking to customers and using lean startup principles.
- We forget nearly everything we are exposed to over time without reinforcement.

Deconstruct the Skill
- Break the skill into various small parts, remembering that every big skill is a collection of many sub-skills.
- Identify the essential sub-skills needed to give you the maximum advantage.
- Practice the most important part that you have discovered, using the 80:20 principle in your learning.
80/20: Pareto's principle
The Pareto principle states that 20% of your activities (even lesser) deliver 80% results (even more) in almost every area of your life.

The Half-Life of Facts
Facts decay over time. And the time it takes to disprove or replace half of it can be predicted.
Data in medicine become half as relevant in 2-3 years. For exact sciences, 2-4 years.
Half life of facts and compound knowledge
If we want our knowledge to compound, we’ll need to focus on the invariant general principles.
Half-lives show us that if we spend time learning something that changes quickly, we might be wasting our time.

The five-hour rule
No matter how busy successful people are, they always spend at least an hour a day (thus five hours a week) learning or practicing. And they do this across their entire career.

Read
Besides expanding your knowledge, reading can give you a good head start; this is often what your peers cannot obtain.
Even if you can't commit to an hour or more of reading every day, start with 20 to 30 minutes.
Reflect
The five-hour rule also includes reflecting and thinking. This could be just staring at the wall or jotting down your thoughts.
Focusing on the past gives you a chance to learn from mistakes you've made, as well as assess what you did correctly. As a result, you’ll be better suited to achieve your goals and improve your life.
