hey guys im starting to read APPS, which was written by matt janda.
to be honest, the concepts in the book are pretty hard to understand for me.
so i thought of two options.
First: keep reading the book until i understand.
Second: finding another resource of GTO, such as watching GTO videos from RIO, and get back to the book.

I did not try to watch gto videos in RIO, but am pretty sure they are much easier to understand than reading APPS.

any suggestion plz?
