when I teach an instrument student, I try and keep it monkey simple. At every fix they must do the 5 t's(turn, time,twist,throttle,talk.) They may not need to do one, but they have to say it out loud. If you do this you will not miss a 10 degree turn at a final approach fix or forget a time on a ndb or forget that you can descend. All those fun things that can get you. hope this explains things better.
