"Rome was not built in a day, neither is character formed in one moment" is a truth I remind myself of often. As I age and experience the loss of those with whom I have shared relationship, the concept of legacy becomes more apparent. 

Our every action is similar to throwing a stone into water. There is an initial splash then the ripples spread and seem to disappear. Truth is even though we can no longer see the energy spread, it continues below the surface and on some scale infinitely. My best suggestion is to keep in mind the stones that were set as a reminder and strive to seek Him and His legacy will shine in yours.
