In a peculiar sense the Forester depends upon public opinion and public support for the means of carrying on his work, and for its final success. But the attention which the public gives or can give to any particular subject varies, and of necessity must vary, from time to time. Under these circumstances, it is inevitable that the Forester must meet discouragements, checks, and delays, as well as periods of smooth sailing. He should expect them, and should be prepared to discount them when they come. When they do come, I know of no better way of reducing their bad effects than for a man to make allowance for his own state of mind. He who can stand off and look at himself impartially, realizing that he will not feel to-morrow as he feels to-day, has a powerful weapon against the temporary discouragements which are necessarily met in any work that is really worth while. Progress is always in spirals, and there is always a good time coming. There is nothing so fatal to good work as that flabby spirit under which some weak men try to hide their inefficiency--the spirit of "What's the use?"
It has been the experience of every Forester, as he goes about the country, to be told that a certain mountain is impassable, that a certain trail can not be travelled, that a certain stream can not be crossed, and to find that mountain, trail, and stream can all be passed with little serious difficulty by a man who is willing to try. Most things said to be impossible are so only in the mind of the man whose timidity or inertness keeps him from making the attempt. The whole story of the establishment and growth of the United States Forest Service is a story of the doing of things which the men who did them were warned in advance would be impossible. Usually the thing which "can't be done" is well worth trying.
Perhaps I ought to add that I am not urging the young Forester to disregard local public opinion without the best of reasons, or to rush his horse blindly into the ford of a swollen stream. Good sense is the first condition of success. I am merely saying that in ninety-nine cases out of a hundred, when a thing ought to be done it can be done, if the effort is made with that idea in mind.
