Twenty Percent

Who uses keyboard shortcuts?

I think everyone agrees, using the keyboard shortcut can save your time. If you shave off 5 seconds by using a keyboard shortcut on a task that you do 50 times a day, do you realize that in 5 years, you just saved yourself 5 days?

Who remembers all existing keyboard shortcut?

I absolutely believe no one knows all existing keyboard shortcut, and no one should. Do you realize that you don’t need to remember all keyboard shortcut but only the most frequently used to gain the most from productivity?

In this writing, I will describe this phenomenon, walk through other similar examples, and how you can apply it to your daily life or works.

Pareto Principle, this phenomenon called with, states that, for many events, roughly 80% of the effects come from 20% of the causes. In another word, 20% of your activity give you 80% of the result. Isn’t it interesting? Doing nothing, you receive nothing. Doing 20%, you receive 80%. Doing the remaining 80%, you got the remaining 20%. It can be demotivating, to know that your 80% hard works, might worth almost nothing.

Unfortunately, a lot of events follow this principle.

80% of your company revenue comes from 20% of your customer.
80% of the world wealth, owned by 20% of people.
80% of software issue comes from 20% bugs.
80% of your expense, comes from 20% of your bill.

In reality, this ratio simply a number. It can mean 90/10, 95/5, or even 99/1.

How many of all your tv series that you follow you actually like?
How many of clothes in your wardrobe you actually use?
Have you ever heard that you are the average of your 5 closest friends?

All right, I got it. A lot of things aren’t actually that useful. Now what?

Simple. Choose your 20%. Look into your task, and choose the 20% that give the most importance. 80% of what you spent your money on might not be that useful. Look into your hobby, what gives you 80% happiness? Look into the keyboard shortcut, what 20% activity you keep repeating and do over and over?

What is your a fifth?
