Brevity

"Brevity is the soul of wit"
- William Shakespeare

"Avoid unnecessary words"
- Strunk and White, The Elements of Style

Usually, the fewer words you use to communicate something, the stronger your writing. If the extra words don't communicate anything, leave them out.

Consider this example:

"At this moment, we are now planning to leave at 6 a.m. in the morning."

6 a.m. in the morning is obviously redundant. Pick one or the other. There are some subtler problems, too.

"At this moment... now" - these two phrases say the same thing. You could choose one or the other. But do you really need either one? "We are planning to leave" is in the present tense. "We are planning to leave" says the same thing as "now we are planning to leave."

"We are planning to leave at 6 a.m." We have trimmed away most of the fat. There is room for just a little bit more improvement. "We plan to leave" is better than "we are planning to leave."

We can remove more than half of the sentence without losing any of the original meaning:

"We plan to leave at 6 a.m."

The sentence can be made just a little bit shorter, but the meaning changes slightly:

"We will leave at 6 a.m." Obviously, if you say you will leave at six, you must be planning to leave at six.

Don't make your readers hunt for something meaningful in an ocean of words. Figure out what you're trying to say, say it, and don't say anything else.
