The Enneagram has been used for personal growth around the world since 1970 and is an amazingly insightful tool that has been used in settings as varied as the Vatican, the CIA, Motorola, the US Bureau of Mines and the Prudential. If you want to find out more, I suggest you read Personality Types by Don Richard Riso with Russ Hudson, revised edition published 1996 by Houghton Mifflin or The Enneagram by Helen Palmer, published 1991 by Harper San Francisco.
The following is a brief summary of each type, based mainly on the work of Don Richard Riso and Russ Hudson, but with the labels used by Helen Palmer also shown.
In each description, the first name is the one used by Riso, the second is the label used by Palmer, and the following words are descriptions of the type - going from healthy to unhealthy. Finally, there is an example of a famous person who Riso suggests may be the type - you decide how far they fit the healthy descriptions!

Type 2 The Helper The Giver nurturing, concerned, possessive, manipulative Mother Teresa
Type 3 The Motivator The Performer self assured, adaptive, image-conscious, deceiver Tony Robbins

Our pathway to development and integration is to move to another number, along the following sequences:
1 to 7 to 5 to 8 to 2 to 4 to 1 or 9 to 3 to 6 to 9
Under stress we are likely to move in the opposite direction! This information is only brief but you can probably identify a type or types that seem to match you. Check then whether you move towards the appropriate numbers when under stress and when things are going well for you.
