Way of the Will?

Before I start I want to say thank you to all you experienced CMers that take your time to reply to posts.  I read when I can and am encouraged by many reponses and threads. 

As for the Way of the Will.  So far it seems to be based off of giving the children opportunities to do what they should instead of what they want.  Sounds great.  Any abc or 123 on how to do that?  I do see a big difference between obedience and the will, especially as being what the child will do when no one is watching.  How does training the will’s of your children (doing what is right when what they want is different) look like in your family?  Thank you soooooo much!!

If it matters, I have 22mo, 3.5yo, 6yo, 8yo.
