The difference between a successful small business and a passing fad depends upon your willingness to evolve and explore innovative ways for your business to meet a market need.
In the small business community, we call this concept pivoting.
A pivot [noun] is a person or thing upon which progress depends. To pivot [verb] means to turn and change direction while depending on the central point. As a veteran, this concept is not so different from changing your mission in the military: while the central goal is the same, the tactics you use may change in order to achieve the goal.
