Whats the central idea for "life of Alexander" by plutarch

Plutarch wrote of the Battle of Issus: “Fortune certainly presented Alexander with the ideal terrain for the battle, but it was his own generalship which did most to win the victory.”[22] This may have been a response to the Vulgate claim that Alexander's luck was responsible for his victories.

The central idea for "Life Of Alexander" by Plutarch is:

       Since he was more inclined to action and fame than to enjoyment or prosperity, he considered everything that he could earn from his father as a reduction and prevention from his own life in the future; and he'd rather have preferred to excel in the empire of difficulty and battle that would have made him regular.

idk i just need the points

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.
