Your first ambition should be the acquisition of knowledge pertaining to your business.
Above all things acquire a good, correct epistolary style, for you are judged by the business world according to the character, expression, and style of your letters.
During business hours attend to nothing but business, but be prompt in responding to all communications, and never suffer a letter to remain without an answer.
Never fail to meet a business engagement, however irksome it may be at that moment.
Undertake no business without mature reflection, and confine your capital closely to the business you have established.
Lead a regular life, avoid display, and choose your associates discreetly, and prefer the society of men of your own type.
