For those who have asked

This is the best book I have found on potty training. I do not suggest that you follow it slavishly, but I do suggest reading it through several times before beginning the process, and taking from it what you can reasonably do. I used this method with minor variations to train all 6 of my children.
For those who asked how I had my children reading at the age of 3, even though I am not into reading out loud, I recommend How to Teach your baby to read. Once again, you can choose what aspects of the program work for you. I just wish that I had taken the time to teach my kids math skills in infancy and toddler hood, as well.
Kids want to learn! and if it isn't fun for both of you, then stop.
