Write in the active, not the passive voice.
This is probably one of the most common mistakes that writers (yes, including myself) make. If you’re unclear as to exactly what I mean by “passive” voice, take a look at this example.
Problem: Passive Voice Constructoin
(noun) (verb phrase) (noun)
Example: “We were invited by our neighbors to attend their party.”
Solution: Active Voice Construction
(noun) (verb) (noun)
Rewrite the sentence to open with “our neighbors” (it’s a stronger sentence opener, trust me):
“Our neighbors invited us to attend their party.”
Note: Yes, it’s challenging, but with time and care in correcting passive voice mistakes you will be on your way to becoming a more proficient writer, because you will have clearly singled out the subject of the sentence.
