Steer clear once for all of useless people and parasites of all sorts—bores, who make you waste your time; indelicate people, who borrow money when they do not know whether they will be able to return it; swindlers, who know perfectly well they will never pay you back a penny. Elbow your way out of all those frauds—poseurs, spongers, leeches, fleas, and bugs—who try to fasten themselves to you.
Be generous, and help a friend in need; devote a reasonable portion of your income to the hospitals, charitable institutions, and the sufferers from public calamities; after that, attend to yourself and to all those who live around you and depend on you for their comfort and happiness.
Bang your door in the face of people who, in your hour of success, come to treat you with a few patronizing sneers in order to take down your pride. Kick down your stairs, even if you live on the tenth floor, the man with an alcoholic breath who calls to tell you that, as you are a fortunate man, it is your duty, and should be your pleasure, to help those who have no luck.
Life is too short to allow you to play the part of a friend to the whole human race. Concern yourself about interesting and deserving people; cultivate the friendship of pleasant men and women, who brighten up your life, and that of useful ones, who may occasionally give you the lift you deserve. Attend to your business; carefully watch over the interests of those who have a right to expect you to keep them in comfort, and dismiss the rest, even from your thoughts.
CHAPTER XI
ADVICE-GIVING
Advice is a piece of luxury thoroughly enjoyed by the one who gives it. If you want to be popular with your friends, do them all the good turns you can. Lend them your money if you have a surplus to spare, and which you can comfortably make up your mind to the loss of, but give them advice when they ask you for it.
People who are lavish of advice are seldom guilty of any other act of generosity. If, however, you cannot resist the temptation of advice-giving, be sure, at least, that you give it in time. People who keep on saying to their friends, 'I told you so,' are the most aggravating bores in the world.
