I have some thoughts already.
I think there is certainly a person in there, with unlimited depth and imagination, but if you can't show something to prove that that inner richness is there, that begs the question of the tree falling in the forest with no one around. That midset motivates taking action to solve problems and work on things, but also is crippling when things aren't going so well.
For instance, if it's a tough time at work, I think I am my performance out there, and when I get home, find it hard to work on hobbies and private dreams, or even to listen to music because it doesn't feel authentic to "real life". Which isn't rational at all, now that I look back on that sentence, but that is how it feels out at the moment. Semiconscious ego shiz, maybe? It's a good thing to question. After all, this is enneagram.
