I'm by no means an expert. However, in my opinion, a good way to start would be to identify your basic fears of the nine within The Enneagram.
Those being, of course:
- The fear of being evil or corrupt.
- The fear of being unloved or unwanted by others.
- The fear of being unaccomplished and worthless.
- The fear of lacking a unique, significant identity.
- The fear of being helpless and inadequate.
- The fear of being without support or guidance.
- The fear of deprivation and pain.
- The fear of being harmed or controlled by others.
- The fear of loss and separation from others.
In addition, identifying the way you express Anger, Shame and Fear is helpful.
- Externalized anger: Openly displayed anger.
- Repressed anger: Avoidance of showing anger openly, but it sometimes manifests as passive-aggressiveness.
- Internalized anger: Harshly criticizing one's self. May also appear as judgmental tendencies.
- Externalized shame: Openly displays shame. May manifest as constantly needing approval or positive feedback.
- Repressed shame: Avoidance of shame. May manifest as trying to prove yourself to avoid the shame that you feel.
- Internalized shame: Keeping shame to yourself. May manifest as failure to believe anyone can understand your pain.
- Externalized fear: Expresses fear openly by displaying paranoia through hoarding, (Information, possessions) as well as detachment.
- Repressed fear: Avoidance of showing fear. May manifest as surrounding yourself with safety/security and suspiciousness of the unknown.
- Internalized fear: Keeping fear to yourself. May manifest as engaging in fun activities to avoid facing the fear contained within.
