Also known as the Pareto Principle, this rule states that across all industries, activities, and contexts, 80% of results come from 20% of causes – e.g. 80% of sales come from 20% of clients; 80% of software problems are caused by 20% of bugs.
When it comes to your work, target the 20% of tasks and actions that will get you 80% of your results, and you’ll have turbocharged your effectiveness with less effort, minimizing time wasted on low-yield activities.
