I've been doing a lot of walking on my treadmill due to dislocating my shoulder a few weeks ago. It was the only exercise that allowed me to really work up a sweat. :) I was getting bored with just listening to my music so I decided to dig out my portable DVD player. I've got tons of movies and TV shows, so started playing those while I was walking. Wow, what a great way to forget about how long I've been walking! I get into the movie or show and the time just flies by.

 I have also found a good way to stay on the treadmill.  I set my DVR to record my favorite soap opera while I am at work, then I play it back while walking.  I vow to stay on the treadmill until the show is over, but allow myself to fast forward thru the commercials.  This gives me a good 40 minute workout, and it goes by really fast!  Keep up the good work!
