The Math Behind The 5-Hour Rule: Why You Need To Learn 1 Hour Per Day Just To Stay Relevant

When we consider the future of work, there are two trends we should keep a note of. They are:

1. Half-life of knowledge
2. Law of increasing learning

The rate at which knowledge is becoming outdated is predictable and growing exponentially.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.

Informal learning outside of traditional institutions accounts for 70 to 90 percent of all learning.

If other people are learning more, then you have to learn just as much to stay relevant. If you don't, you will fall behind. If you are in your current job, you might not even realize how far you're falling behind. It might only become apparent if you try to transition to a new field or re-enter the market after a break.

You might not think you have five extra hours in the week, but you do. The simplest way is to stack learning on top of your current schedule. Areas where you can leverage double-time every day:

• Driving to and from work
• Exercise
• Socializing (friends can learn together and talk about it)
• Eating and food prep
• Doing housework or yard work.

With smartphones and the explosion of videos, podcasts, and audiobooks, you can learn while you do other things throughout your day.

Just as we have minimum recommended dosages of vitamins and minutes of exercise for maintaining physical health, we should understand that we also have to be rigorous about the minimum dose of deliberate learning that will maintain our economic health.

Those who do not keep learning will be left behind, stuck in a job, or unemployed.
