From "The Story of Charlotte Mason" on the formation of habits:
Almost anything may be made of a child by those who first get him into their hands. We find that we can work definitely towards the formation of character; that the habits of the good life, of the alert intelligence, which we take pains to form in the child, are, somehow, registered in the very substance of his brain; and that the habits of the child are, as it were, so many little hammers beating out by slow degrees the character of the man. Therefore we set ourselves to form a habit in the same matter-of-fact steady way that we set about teaching the multiplication table; expecting the things to be done and done with for life. But fitful efforts after a habit - say of tidiness, or of obedience - are of very little use, and are worrying to child and parents.
The list of habits to be established in your children can make habit training seem to be a daunting task. One thing that eases my mind is knowing that each child has natural tendencies. Some are negative and some positive. Jonathan is naturally neat and tidy. He likes to put things back in their place. (Oh how thankful I am for that tendency!) But he also likes to take his time in the tub while bathing. So I make sure that he continues his tidiness while working with him on dawdling. Noticing these places where work is needed for each individual child and then mapping out a plan (seek advice, especially from your spouse who is a necessary part of habit training) makes more sense to me than simply choosing habits from a list. I also don't have to remind myself to train in these areas because their sneaky faces show themselves often enough to bug me to remembrance. Over and over again - making sure the good habit is being done. Soon it will be established and will take more effort for them to choose the "old way" than for them to just do what they've been trained in. And what a better life your children will have because of the time you've taken though it is hard work right now.
