The Art of Worldly Wisdom(104)

Know the demands of different occupations. Varied qualities are required. To know which is needed taxes attention and calls for masterly discernment. Some demand courage, others tact. Those that merely require rectitude are the easiest, the most difficult are those requiring cleverness. For the former all that is necessary is character; for the latter all one's attention and zeal may not suffice. It is a troublesome business to rule people, still more fools or blockheads: double sense is needed with those who have none. It is intolerable when an office engrosses someone with fixed hours and a settled routine. Those are better that leave him free to follow his own devices, combining variety with importance, for the change refreshes the mind. The most in repute are those that have least, or most distant, dependence on others; the worst are those that worry us both here and hereafter.
