I'm no expert on the id, ego, superego concept, but here is my understanding very simplified:

Id = our basic primal needs (so according to you T, that girl who longs for those needs to fulfilled is you id).

Superego = our moral center, doing want we believe society wants and accepts, the "shoulds" (this would be that honor roll student side of you)

Ego = the balance between those where we can see clearly what we need and how to get it in acceptable, rational ways (more or less)
