In our daily lives we are accustomed to a certain sequence of events where we expect everything to have a beginning, a middle and an end. Major life transitions upset the natural order of things since they require moving from an ending of the way things used to be to the beginning of a new phase in life. This means you need to be prepared intellectually, emotionally, psychologically and spiritually to transition into a meaningful and purposeful life after all of the old rules, roles, structures and sources of support evaporate, with the end result being complete personal transformation.
As your youngest child transitions out of the house, you and your spouse are also transitioning into a new relationship which can provide new growth and opportunities if properly planned. The same is true if you are a single parent.
