[10.] Use the active voice.
The active voice is usually more direct and vigorous than the passive:
I shall always remember my first visit to Boston.
This is much better than
My first visit to Boston will always be remembered by me.
The latter sentence is less direct, less bold, and less concise. If the writer tries to make it more concise by omitting “by me,”
My first visit to Boston will always be remembered,
it becomes indefinite: is it the writer, or some person undisclosed, or the world at large, that will always remember this visit?
This rule does not, of course, mean that the writer should entirely discard the passive voice, which is frequently convenient and sometimes necessary.
The dramatists of the Restoration are little esteemed to-day.
