Limit your time in previewing and postviewing to about 10 minutes for a book. You'll collect enough trigger words to get started without overwhelming yourself.
During activation you will find answers and perhaps create other questions and that's the purpose of activating in layers. You progressively build conscious comprehension in layers and build your mind map in layers.
Make a 20 to 25 trigger word list your limit. You won't miss anything; they are your starting point. Sometimes less is more.
