Reading procrastination

My eyes are either too tired to read, or I find something more distracting to occupy my time with such as the Internet.  Or I don't remind myself to continue a book.  What are some good ways to motivate yourself?

I have not actually finished a book for months. I always start a
book, get past a few pages, and then bookmark it and stop. I think I have a good 10 books lying around in my room bookmarked into a few pages.
