Criminal Sentence 201: Keeping Sentences Parallel

From a book I finished yesterday:

"He was smart, decisive and had sound judgment."

And a couple pages later:

"He has graying hair, a calm voice and never seems to hurry."

Both of these suffer from the same problem: The parts don't fit together right. Make a list and you'll see what I mean.

He was smart
decisive
had sound judgment

He has graying hair
a calm voice
never seems to hurry

Both sentences are missing a verb in the middle. One way to fix it is to add the missing verb:

He was smart
was decisive
had sound judgment

He has graying hair
has a calm voice
never seems to hurry

If you want to avoid repeating a verb, you can rewrite the sentence. One way:

Smart and decisive, he had sound judgment.
With graying hair and a calm voice, he never seems to hurry.
