Finding a well-paying job is hard. Finding a well-paying job that you like might be even harder.

To better gauge employee preferences in the workplace, 80 percent of Fortune 500 companies and 89 of the Fortune 100 companies have used the Myers-Briggs Type Indicator (MBTI), according to CPP, the exclusive publisher of the Myers-Briggs test.

The assessment categorizes people according to the following eight characteristics:

Extraversion (E) or Introversion (I)

Sensing (S) or Intuitive (N)

Feeling (F) or Thinking (T)

Judging (J) or Perceiving (P)

In a personality type and career achievement study by Molly Owen, CEO of career assessment publisher Truity Psychometrics, a survey of 1,505 found that those with the ESTJ personality type earn the highest average yearly income.

In this survey, the average female ESTJ's annual income was $68,000 while the average male ESTJ earned $95,000 a year.
