100 Examples of the 80/20 Rule

Also known as:

  1. The Pareto Principle
  2. The Principal of Least Effort
  3. The Principal of Imbalance
  4. The Law of the Vital Few and the Trivial Many
  5. The More with Less Principal

The Rule

The 80/20 Rule asserts that a minority of causes, inputs, or efforts usually lead to a majority of the results, outputs, or rewards. The 80/20 split is not hard-and-fast as to every situation. It's a scientific theory based on empirical data. The real percentages in certain situations can be 99/1 or an equal 50/50. They may not add up to 100. For example, only 2% of search engines hog 96% of the search-engine market. Fewer than 10% of drinkers account for over half of liquor sold. And less than .25% of mobile gamers are responsible for half of all gaming revenue.

Origin

In 1897, Vilfredo Pareto, an Italian economist, observed that 20% of pea pods in his garden produced 80% of the peas. He then applied the same logic to land distribution in Italy and found that 80% of the land was owned by 20% of the population. In 1949, George Zipf, American economist at Harvard, rediscovered this rule after World War II. Then in 1979, British author, Richard Koch, wrote the best-selling book, The 80/20 Principle. This blog post captures some powerful content in his book.

35 Key Insights and Takeaways:

  • Life is nonlinear. Forces of life are imbalanced. Some forces are just more important.
  • People who employ 80/20 thinking are good at achieving happiness.
  • Effective 80/20 thinkers are masters at prioritizing and delegating the rest.
  • Pick tasks with the highest reward that require the least effort.
  • Life-changing insight requires consistent, high-value thinking and reflection.
  • Solve problems by removing impediments. Like the World Wide Web did by removing distance or like fast food restaurants did by removing waiters.
  • Laziness is a human trait and should be capitalized.
  • Focus increases individuality, which is the essence of being a human being.
  • Do more with less not more with more.
  • Never sacrifice time or love for money.
  • Move quickly. Doubt, procrastination, and over-analysis sap energy.
  • Focus on the value, disregard the waste. Resources that have weak effects should be ignored.
  • Successful people identify value and adapt themselves to the world.
  • Decisions based on superior economics always yield the highest returns.
  • Convert your best talents into economic wealth.
  • Capitalize on your "20% spike" of individuality to achieve rock-star success.
  • Success is caused by steady application and sudden insight.
  • Use this strategy to work 2 days per week with 60% more productivity.
  • Disassociate effort from reward.
  • Free your guilt.
  • Practice spending your time unconventionally to arrive at what suits you perfectly.
  • Enjoyment predicts success, not effort or education (although applying effort and education to what you enjoy will obviously catapult your success). For example, Ronald Reagan effortlessly moved from actor to president. He focused on what he felt passionate about (taxes, inflation, and communism). Warren Buffet's working style, admittedly, "borders on lethargy." He sits in his office and does what he loves.
  • Go deeply and narrowly. Learn 99% of a topic and ignore the rest.
  • Develop the facility to mentally block out the bottom 80%.
  • Specialize in something that fills you with enthusiasm and passion.
  • Act less. Action drives out thought, and it's the thought that directs meaningful action.
  • Time management isn't the problem. We're awash in time. Time use is the problem. Most genius work is done in relatively little time.
  • Achievement is driven by insight and selective action.
  • Knowledge = power.
  • Know your market.
  • Become self-employed early.
  • Employ net-value creators.
  • Outsource everything that isn't within your core competencies.
  • Leverage capital (both human and money).
  • Learn from the best.
