I say, plan to earn your living! Whether you actually earn the money you live on, makes no great difference, though in your case I guess you'll have to if you are going to live at all well. But if you get money without earning it, it leaves you in debt to society. Somebody has to earn the money you spend. In mine, factory, railroad, or office, somebody works for the money that supports you. No matter where the money comes from, that is true: somebody has to earn it. If you get it without due labor of your own, you owe for it. Recognize that debt and qualify yourself to discharge it. Study to put back into the world somewhat more than you take out of it. Study to be somewhat more than merely worth your keep. Study to shoulder the biggest load your strength can carry. That is life. That is the great sport that brings the great compensations to the soul. Getting regular meals and nice clothes, and acceptable shelter and transportation, and agreeable acquaintances, is only a means to an end, and if you accept the means and shirk the end, the means will pall on you.
I said 'agreeable acquaintances.' A very large proportion of the acquaintances you can make will be agreeable if you can bring enough knowledge and a sufficiently hospitable spirit to your relations with them. I don't counsel you to cultivate the arts of popularity, for they are apt not to wash,--apt, that is, to conflict with inside qualities that are vastly more valuable than they are. But keep, in so far as you can, an open heart. There is no one to whom you are not related if only you can find the relation; there is no one but you owe him a benefit if you can see one you can do him.
Don't be too nice. It is such an impediment to usefulness as stuttering is to speech,--a sort of spiritual indigestion; a hesitation in your carbureter. By all means, be a gentleman, in manners and spirit, in so far as you know how, but be one from the inside out.
If you had come as far as you have in life without acquiring manners, you might well blush for your parents and teachers. I don't think you have, but I beg you hold on to all the good manners you have, and get more. Good manners seem to me a good deal to seek among present-day youth, but I suppose they have always been fairly scarce, and the more appreciated for their scarcity. Tobacco manners are uncommonly free and bad in this generation; more so, I think, than they were in mine. Since cigarettes came in, especially, youths seem to feel licensed to smoke them in all places and company. And the boys are prone to too much ease of attitude, and lounge and loll appallingly in company, and I see them in parlors with their legs crossed in such a fashion that their feet might almost as well be in the ladies' laps.
