Actually the WIIFM is the question I have in mind when I PhotoRead books in the bookshop. My "purpose" is to find anything useful to me that is relevant to me in my life right now or in the near future. I don't need to make a long prose like that anymore when I establish my purpose and when I am PhotoReading books it's nearly always my starting point and first purpose when I pick up a book.

WIIFM is the one of the first relevant mind probing question based the purpose of deciding if there is any point in proceeding further with this book.

No. WIIFM isn't a purpose, it is a mind probing question and as you have pointed out the reason it worked is you had an underlying purpose even if it Was difficult to explain in a way that showed others that you did have a purpose.
