Greatest psychology book and class?

What books is prequiste in order to become a pyschogist? Which theraphy should one study, which is popularly used?

“On the Genealogy of Morals” by Nietzsche taught me just about everything to get started in psychology.
Also, it’s worth reading, “The Ego and the Id”, and “Civilisation and its Discontents” by Freud.

Ald, a real psychologist, recommended these:

behavior.net/gestalt.html
existentialpsychotherapy.net/

Books: The first guy invented the idea.

If Ald’s attitude is indicative of how he practices, I’m not so sure that is the fdirection you want to go . . . .

But I found them quite informative.
