Visualization is the mental homework.
This technique is helpful in seeing your stoke from the outside in. Internal visualization is being there, seeing yourself through your own eyes and mind. The internal technique is very effective since you are on the inside and can re-create not only images, but feelings . To feel the feelings is very important so that when we are in a competitive situation, we are not surprised by certain feelings, and can often regulate them. Pain - these are all parts of competing.
