We should have little respect for a private gentleman who did not exert himself to gain an estate, or even a considerable office, when he could acquire them without either meanness or injustice. A member of parliament who shows no keenness about his own election, is abandoned by his friends, as altogether unworthy of their attachment.

We should have little respect for a private gentleman who did not exert himself to gain an estate, or even a considerable office, when he could acquire them without either meanness or injustice. A member of parliament who shows no keenness about his own election, is abandoned by his friends, as altogether unworthy of their attachment. Even a tradesman is thought a poor-spirited fellow among his neighbours, who does not bestir himself to get what they call an extraordinary job, or some uncommon advantage. This spirit and keenness constitutes the difference between the man of enterprise and the man of dull regularity.” source
