When the time for action has come, the moment must be quickly seized. Just as water first collects in a lake without flowing out, yet is certain to find an outlet when the lake is full, so it is in the life of man. It is a good thing to hesitate so long as the time for action has not come, but no longer. Once the obstacles to action have been removed, anxious hesitation is a mistake that is bound to bring disaster, because one misses one's opportunity.
