If you can once engage people's pride, love, pity, ambition (or whatever is their prevailing passion) on your side, you need not fear what their reason can do against you.
There is nothing so necessary, but at the same time there is nothing more difficult (I know it by experience) for you young fellows, than to know how to behave yourselves prudently towards those whom you do not like. Your passions are warm, and your heads are light; you hate all those who oppose your views, either of ambition or love; and a rival, in either, is almost a synonymous term for any enemy.
