To understand this model, the vertical axis represents satisfaction, or happiness, and the horizontal axis represents time. The first stage, often called the honeymoon stage, happens right at the beginning of the journey.
Im sure most if not all of us know what the honeymoon stage and how it works. I liked how they used this word to reference cultural shock and how it plays a major part in the beginning of the journey. I think it's important to realize that before making any huge changes.
