What is the moral of story the old man and the sea

From the book the Old Man and the Sea, several morals are observed. For instance, Santiago demonstrates persistence in his fishing endeavor. Despite going for more than eighty days without a single catch, each evening going home empty-handed, Santiago does not relent and still goes out to fish. Humility is also shown when Santiago accepts Manolin’s kindness. He put aside his pride and accepted assistance from a young boy that pitied him. Manolin portrays loyalty by ensuring that Santiago has enough to eat. He also ensures that Santiago has fresh bait for his lines, going to the extent of stealing or begging to make sure the above needs are met. He does all this despite his father’s advice to stop associating with Santiago. Santiago demonstrates patience by pursuing the marlin overnight, waiting for it to tire. He is resourceful, eating raw tuna. He also consumes water carefully not to exhaust it, aware that he is long way from shore.

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
