Do you consider whether you write in active voice vs. passive voice? You should. Active voice makes for clearer, more concise, and more vigorous writing.

Don’t write:
Tests were run and it was determined that errors still exist in the program.
Write:
Testing showed that errors still exist in the program.
Or:
We ran the tests and found that errors still exist in the program. (This one shows ownership.)

Tip 22 from Strunk and White: “Place the emphatic words of a sentence at the end.”  Example:

Don’t write: “Humanity has hardly advanced in fortitude since that time, though it has advanced in many other ways.”

Write:  ”Since that time, humanity has advanced in many ways, but it has hardly advanced in fortitude.”
