Life is always changing in Nature. It is a constant. All new things created are in mathematical portions as all the things before them. While life in nature seems to be haphazard, it is not.
Life for humans is always changing. However, it seems human growth and development is fettered. Creativity is thwarted. You MUST color between the lines and follow the rules.
Life, by its definition, is creativity. Thus, we should create whenever the mood strikes us. Today, do something outside your norm. Be creative. Walk on the road, where you can, and not on the side walk. Does it feel different?
