This chart was invented by Charles F. Haanel back in 1916 and he used it as a pamphlet to get people interested in buying his book The Master Key System.

Ever felt you’re not using your full potential?

So many people (myself included) feel there’s so much more we could do with the hours we have each day…

But... it’s hard to know what or where to focus on!

Enter the ‘Psychological Chart’.

Psychological Chart

This chart was created by Charles F. Haanel back in 1916 and he used it to get people interested in his book The Master Key System

You see, people have felt this way for centuries.

So what did Haanel do?

He created a chart that helps you figure out which aspect of your ‘brain power’ you need to focus on to start improving your life.

Here’s a re-creation of the chart (see left image).

All you need to do is fill out the chart from top to bottom with the % you feel you’re currently using.

Here’s an explanation of each:

  • Mental Product.
    Charles F Haanel asks ‘are you getting full value for your mental product?’. In other words, are you getting paid the full value of what you have to sell, your knowledge, your experience, your loyalty, your energy? If you are fully marketing your mental product put 100%. But if not, put a lower % and be fair to yourself – consider how much money others are making who do not have the skills or experience that you do.
  • Health.
    Can you go about your day without any consideration of thought for the state of your health? If so you can put 100%. But if you are worried about what or what not to eat, if you can’t sleep, or if you have aches and pains of any description then deduct from 100% to the fairest percentage.
  • Time Efficiency.
    Charles F. Haanel says that if you work 8 hours, sleep 8 hours and use the remaining 8 hours for recreation, study and self-improvement then you can put ‘100%’. But if you spend your hours in idleness or wasted efforts or procrastination then reduce the percentage.
  • Creative Power.
    Charles F. Haanel calls your ‘creative power’ a measure of the effort you need to put into achieving whatever you want. For example, if you need huge will power, or worry over an upcoming challenge or interview or task, then cut your percentage down to ‘50%’. If there is any ‘anxiety’ over your work or pursuits then cut down accordingly.
  • Concentration.
    Here he writes ‘Can you direct thought to any problem which may arise for fifteen minutes to the absolute exclusion of everything else?’. If so, put 100%. But if you are haunted by fears or troubles or anxieties or ‘create problems for yourself’ then cut down this percentage.

You add up all the percentages to create the ‘Total’.

Then, divide by 5 to get the average.

This is the percentage of ‘brain power’ you are currently using in your day to day life!


Of course, this is a personal assessment... It’s not scientific.

But if one of the rows has a low percentage then you know exactly what you need to focus on.

Charles F. Haanel writes that improvement in any one of these areas can affect the others:

“Again, any method which would bring you health, efficiency in your time, efficiency in your creative power, or increase your ability to concentrate, would be worth at least $1,000 a year [in your mental product].”

$1,000 in 1916 is worth about $30,000 today – it’s a lot!

And guess what?

The Master Key System is the perfect resource to help you improve in any one of these areas of your life.
