I was listening to a shiur by Rav Fishel Schachter recently, and he said that in their community, a 20 yr old girl suffered from a stroke and could not open her eyes, so some people in shul took upon themselves to be very careful with shmiras aynaim. One guy who drives a truck, put her name on his dashboard to remind him not to look where he shouldn't. After some time, she was finally able to open her eyes.
Two things I learned from this, one, the power of "middah k'neged midda", and two, that sometimes we need a physical marker or reminder to keep us going. Our mind play tricks on us, so that man used a piece of paper with a choleh's name on it.
We too should try to think of something more concrete that we can look at, to remind us not to stray. Maybe a picture of a Gadol next to our computers...
