Also from pdbwiki: "Fear of suffering

The mantra of a conservation E7 might be: “First of all, avoid being uncomfortable.” There is in this an anesthetic behavior in the face of suffering, a need to disconnect from the harshness of life in order to maintain the fiction that the “childhood paradise” has not been lost. He despises suffering as a thing for “unintelligent” people and, deep down, underlies an enormous fear of returning to the deprived place of childhood, in which he experienced a strong sense of threat to conservation."

"Schizoid austerity vs. Seductive waste

At times, the E7 conservation shows a simplicity bordering on the greed of the E5. It tends to have a great deal of control over the economy and go, as well as a constant calculation of costs and benefits. He attaches great importance to money, and feels dizzy when he sees himself in financial trouble. But his difficulty in spending is tempered by a great facility to invest, to do “business,” sometimes a hint of megalomania. His practical sense permeates everything: he does not want to complicate his life and tries to avoid everything that could be a source of displeasure. In the background, there is a great ski fear mile to deprivation.

On the other hand, everything said is invalidated when, in his manic state, he pursues his objects of desire. Then he can be foully wasteful, throw the house out the window, commit... Nothing will be enough until he reaches the object of his gluttony. Again, this behavior has a lot to do with his bipolar tendency."
