Someone once said the only thing that likes change is a wet baby. Change represents many things to many people. Unfortunately, most people do not view change in a positive, healthy, and optimistic fashion. This is especially true for any changes that they did not desire or foresee.
It is important when facing any change that you learn to regroup yourself by asking what do I control and what do I not control? This approach immediately puts you in the position of realistically navigating the change. Simply listing the things that you can control and the things that you cannot control puts you mentally and emotionally in control.
Finally, as difficulty as it might sometimes seem, try to discipline yourself to look for the good in the impending change. If you meditate on it long enough, there is always some aspect about the change that you can identify as a net positive. If you take that approach, then you can use the change as some kind of a stepping stone. Others have done so, and you can too. I like the way Judy Vredenburgh (CEO of Girls, Inc.) summarizes this (“How Did I Get Here?: Judy Vredenburgh” Bloomberg Businessweek, 10/19/15–10/25/15, p. 80):
“See obstacles and change as opportunities.”
