One of the Seven Wise Men of Greece boiled his wisdom down into two words,--NOTHING TOO MUCH. It is a rule which will apply to food, exercise, labor, sleep, and, in short, to every part of life. This is not so very difficult a matter if one begins in good season and forms regular habits. But what if I should lay down the rule, Be cheerful; take all the troubles and trials of life with perfect equanimity and a smiling countenance? Admirable directions! Your friend, the curly-haired blonde, with florid complexion, round cheeks, the best possible digestion and respiration, the stomach of an ostrich and the lungs of a pearl-diver, finds it perfectly easy to carry them into practice. You, of leaden complexion, with black and lank hair, lean, hollow-eyed, dyspeptic, nervous, find it not so easy to be always hilarious and happy. The truth is that the persons of that buoyant disposition which comes always heralded by a smile, as a yacht driven by a favoring breeze carries a wreath of sparkling foam before her, are born with their happiness ready made. They cannot help being cheerful any more than their saturnine fellow-mortal can help seeing everything through the cloud he carries with him. I give you the precept, then, Be cheerful, for just what it is worth, as I would recommend to you to be six feet, or at least five feet ten, in stature. You cannot settle that matter for yourself, but you can stand up straight, and give your five feet five its--full value. You can help along a little by wearing high-heeled shoes. So you can do something to encourage yourself in serenity of aspect and demeanor, keeping your infirmities and troubles in the background instead of making them the staple of your conversation. This piece of advice, if followed, may be worth from three to five years of the fourscore which you hope to attain. If, on the other hand, instead of going about cheerily in society, making the best of everything and as far as possible forgetting your troubles, you can make up your mind to economize all your stores of vital energy, to hoard your life as a miser hoards his money, you will stand a fair chance of living until you are tired of life,--fortunate if everybody is not tired of you.
