The reason why change is important, it affects all of us at some point and time in life. If we do not experience different things, then we still and will not grow in our everyday lives.  It becomes very important to recognize when there is a need for change. When our lives plateau or we feel the the need to improve in some way. We then need to make the necessary steps to make us happy and satisfied. Because without that progression, everyday life is monotonous and each day is the same as the preceding one. Every so often change something just for the challenge. Challenge is growth.
