In 1984, I was introduced to the DISC Personal Profile System now known as the DISC Classic. I found it to be extremely helpful in gaining a deeper insight to myself and having a general understanding of others.
There are 24 groups of descriptive words in this self-administered instrument. You are to select one that MOST describes you and one that LEAST describes you. From your choices, three graphs are plotted. The DISC profile shows

With varied activities
Social recognition
Freedom from control and details
Opportunity to influence others
Consistent and familiar
Offers an area of specialisation
Working with a group

Clearly defined job description
