What are the motifs in Celebration of Discipline by Richard J. Foster?

Celebration is part of the title as well as an important ideas in the book. What good is change if in the end a person can not celebrate the results? Often people pray for change or for results, and when they receive the answers they forget to celebrate whatever is the response. Any time we enter into communion with God there should be joy and celebration. It is more than an expression of emotion, it the response to subjects or events. It is about finding joy in the knowledge of something or someone. It is to commemorate a special event or memory. It is something a person can choose to do anytime or any place.
