I have always thought that one man of tolerable abilities may work great changes, and accomplish great affairs among mankind, if he first forms a good plan, and, cutting off all amusements or other employments that would divert his attention, make the execution of that same plan his sole study and business.
Benjamin FranklinIf a sound body and a sound mind, which is as much as to say health and virtue, are to be preferred before all other considerations, ought not men, in choosing a business either for themselves or children, to refuse such as are unwholesome for the body, and such as make a man too dependent, too much obliged to please others, and too much subjected to their humors in order to be recommended and get a livelihood?
