The credit belongs to those who are actually in the arena, who strive valiantly; who know the great enthusiasums, the great devotions, and spend themselves in a worthy cause; who at best know the triumph of high achievement; and who, at worst, if they fail, fail while daring greatly, so that their place shall never be with those cold and timid souls who know neither victory nor defeat.
I can no more explain why I like "natural history" than why I like California canned peaches; nor why I do not care for that enormous brand of natural history which deals with invertebrates any more than why I do not care for brandied peaches. All I can say is that almost as soon as I began to read at all I began to like to read about the natural history of beasts and birds and the more formidable or interesting reptiles and fishes.
From the greatest to the smallest, happiness and usefulness are largely found in the same soul, and the joy of life is won in its deepest and truest sense only by those who have not shirked life's burdens.
We cannot afford merely to sit down and deplore the evils of city life as inevitable, when cities are constantly growing, both absolutely and relatively. We must set ourselves vigorously about the task of improving them; and this task is now well begun.

No man can do both effective and decent work in public life unless he is a practical politician on the one hand, and a sturdy believer in Sunday-school politics on the other. He must always strive manfully for the best, and yet, like Abraham Lincoln, must often resign himself to accept the best possible.
Such an experiment without actual conditions of war to support it is a foolish waste of time. . . . I once saw a man kill a lion with a 30-30 caliber rifle under certain conditions, but that doesn't mean that a 30-30 rifle is a lion gun.
The man who really counts in the world is the doer, not the mere critic -- the man who actually does the work, even if roughly and imperfectly, not the man who only talks or writes about how it ought to be done.
If there is one tendency of the day which more than any other is unhealthy and undesirable, it is the tendency to deify mere "smartness," unaccompanied by a sense of moral accountability. We shall never make our republic what it should be until as a people we thoroughly understand and put in practice the doctrine that success is abhorrent if attained by the sacrifice of the fundamental principles of morality.
If a man continually blusters, if he lacks civility, a big stick will not save him from trouble, and neither will speaking softly avail, if back of the softness there does not lie strength, power.
