1. Starting with the Basics: Introducing the 80 of 90 Concept
In this section, we’ll be looking at the basics of the 80 of 90 concept and what it entails. At its core, the 80 of 90 concept focuses on the idea that 80% of your outcomes come from 20% of your inputs. This means that by focusing on the most important 20% of your efforts, you can achieve 80% of your desired results.
This concept can be applied to just about anything, from managing your time to marketing your business. For example, in time management, you might find that 80% of your productivity comes from the 20% of tasks that are most important. By identifying these tasks and focusing on them first, you can achieve more in less time.
Similarly, in marketing your business, you might find that 80% of your revenue comes from 20% of your customers. By identifying these customers and catering to their needs, you can increase your revenue without wasting time and resources on less profitable customers.
Of course, the exact percentages may vary from situation to situation, but the key takeaway is that by focusing on the most important inputs, you can achieve the greatest outcomes.
Now, you might be wondering where the “90” comes in. While the original concept focused on the 80 of 20, the 80 of 90 concept takes things a step further. It suggests that by focusing on the top 10% of your inputs (the 90 in the equation), you can achieve even greater outcomes.
So, for example, let’s say that you’ve identified the 20% of your efforts that produce 80% of your outcomes. To take things to the next level, you could then identify the top 10% of actions within that 20% that have the greatest impact. By focusing on these key actions, you can achieve even greater results.
- To summarize:
- The 80 of 90 concept focuses on the idea that 80% of your outcomes come from 20% of your inputs.
- By focusing on the most important inputs, you can achieve the greatest outcomes.
- The 80 of 90 concept suggests that by focusing on the top 10% of your inputs, you can achieve even greater outcomes.
So if you’re looking to improve your productivity, marketing efforts, or anything else, start by identifying the most important inputs and focusing on those. Then, take things to the next level by identifying the top 10% of actions that have the greatest impact. By doing so, you can achieve greater success with less effort.

5. Real-Life Examples: How to Apply 80 of 90 in Everyday Scenarios
Are you struggling with applying 80 of 90 in your daily life? Here are some real-life examples of how you can use it.
1. Prioritizing tasks
Using the 80/90 rule when prioritizing your daily tasks can help you be more productive. Consider which tasks are essential and which ones are urgent. Prioritize the ones that are both essential and urgent, and work on them first thing in the morning when your energy levels are high. Then, move on to the non-essential tasks.
2. Making decisions
The 80/90 rule can also help you make better decisions. When you’re faced with a tough decision, take the time to gather as much information as possible. Then, think about which options will have the biggest impact on your life goals. Focus on the options that have an 80 percent chance of success, and ignore ones that don’t. This will help you make a clear and informed decision.
3. Sticking to a budget
If you want to save more money, try using the 80/90 rule to stick to your budget. When creating your budget, allocate 80 percent of your income to essentials like housing, food, and transportation.

4. Creating habits
The 80/90 rule can also be applied to creating habits. When trying to establish a new habit, commit to doing it for 80 percent of the time. This gives you some leeway for days when you’re feeling low energy or need a break. By committing to the habit for the majority of the time, you’ll be more likely to stick to it long-term.
5. Planning your day
Finally, using the 80/90 rule to plan your day can help you be more productive and less stressed. Start by making a list of all the tasks you need to complete that day.
