Does every boxer look for the same thing or follow the same procedure as soon as they start round 1? I am trying to make myself an organized fighter here mentally. I want to know how to scan my opponent and know what to start with as soon as i begin to square up with him? what is the procedure i know in some instances its always different, but what are some other ways? heres what i know so far:

how he positions his footwork
how he moves
how he reacts to feints
his style
his rhythm
how he reacts to my jab
