In terms of your sitting posture, you should try to sit in an ergonomically correct way, not only for this but in general. (I hunched too much which limited my view. Sitting correctly helped in getting the big picture of where things are on my page)
One thing that has helped me is not holding the pen too far down and resting my pinky knuckle on the page or table. Just be comfortable with the pen and it will come to you. Engaging your shoulder feels weird at first, but you will get the hang of it in time.

Good luck :)
