You can do nothing about the past whether good or bad. It is time to move forward and release all that is behind you. There is nothing you can do to change what was. Some of your decisions resulted in seeds sown that produced regret. But, you can make better choices now that will reap a healthier and more robust harvest. Choose wisely, for you stand on the threshold of a new beginning and new opportunities.
You are beginning to deal with all kinds of change in your life--from slight to radical. Change requires adjustment. If you refuse to be flexible and are unyielding and rigid, it will be a painful experience. Do all that is necessary to accommodate the process of adjusting to things that are different than they were. Let this become a time of growth in all areas of your life.
