The present is the foundation of the future.
This seems so simple, so common sense. Still, I was told the story of an instructor who had plans for his dojo. He was so focused on his plans that he did not realize that his students were not ready, and / or had other plans. The school collapsed.
In order to take good care of the present, one must have a carful eye on the future. And in order to pave wisely the way of the future, one must take good care of the present.
