In displaying the psychology of your characters, minute particulars are essential. God save us from vague generalizations! Be sure not to discuss your hero's state of mind. Make it clear from his actions. Nor is it necessary to portray many main characters. Let two people be the center of gravity in your story: he and she.
... it is a welcome symptom in an age which is commonly denounced as materialistic, that it makes heroes of men whose goals lie wholly in the intellectual and moral sphere.
Unconsciously we all have a standard by which we measure other men, and if we examine closely we find that this standard is a very simple one, and is this: we admire them, we envy them, for great qualities we ourselves lack. Hero worship consists in just that. Our heroes are men who do things which we recognize, with regret, and sometimes with a secret shame, that we cannot do. We find not much in ourselves to admire, we are always privately wanting to be like somebody else. If everybody was satisfied with himself, there would be no heroes.
For the greater a man's works for the future, the less the present can comprehend them; the harder his fight, and the rarer success. If, however, once in centuries success does come to a man, perhaps in his latter days a faint beam of his coming glory may shine upon him. To be sure, these great men are only the Marathon runners of history; the laurel wreath of the present touches only the brow of the dying hero.
One of the worst days in America's history saw some of the bravest acts in Americans' history. We'll always honor the heroes of 9/11. And here at this hallowed place, we pledge that we will never forget their sacrifice.
The shot Irishmen will now take their places beside Emmet and the Manchester Martyrs in Ireland, and beside the heroes of Poland and Sérbia and Belgium in Europe; and nothing in heaven or earth can prevent it.
