I am starting a certificate program in postsecondary reading and annotating was mentioned there, too. Here it is in a nutshell: active participation in the reading process; read with a pencil in hand and make notes; interact with the author (what are they doing?); develop your own marking system; identify the main point, key ideas, specific craft issues, and determine the strengths and weaknesses of the narrative.
My primary admonition would be, if you are a writer and you’re serious about it, do not be lazy about reading. Be rigorous with the narrative, whether reading another’s or writing your own.
