Here is my approach to give some idea. I visited Psychology Department of Peshawar University, studied 3 themes COMPARATIVELY from the recommended books for 5 days in its library; Zimbardo, Myers, Feldman, Morgan and Sdorow. Having got a very good idea of the language, quality of material and the presentation styles of all these books, only then I approached teachers of the department and after consultation, chose MY strategy and book.
The point is not to follow blindly, even the teachers, esp in book selection matter. You will come across varying opinions, as they have their own preferences per their tastes.
My say; don't wait for this good professor thing, most of the themes can be studied by yourself, in only a few things will you genuinely need a teacher's help, even that can be evaded provided having good comprehension abilities. Simply get going.
