No, I think you can, because of the fact that you still have the ability to read; you have the book and at your own discretion, are able and free to go to the next or previous chapters of your book.
I guess, rather than saying:
YOU CAN'T START THE NEXT CHAPTER OF YOUR LIFE IF YOU KEEP ON RE-READING THE CURRENT ONE (rather than saying the LAST as you have suggested, because if someone is reading the last chapter, there naturally cannot exist the NEXT ONE for him/her to go to because the chapter is the last).
You would better rephrase your statement to:
YOU ARE NOT WILLING TO START THE NEXT CHAPTER OF YOUR LIFE IF YOU KEEP ON RE-READING THE CURRENT ONE
