Another of those "marks of a pro" is taut sentences (not necessarily terse) which say exactly what you mean without extra words. These lame words are particularly noticeable at the end of a sentence. (Remember, ending a sentence and esp. a paragraph on a strong word makes them particularly meaningful.)
So as you're revising, look at your sentences-- read them aloud, and listen for the bump or the lag that tells you the sentence has lost its power. Challenge yourself to make every sentence snap.
One thing I've noticed in editing is that the old grammarians were right (for the wrong reason, of course)-- ending a sentence on a preposition is usually bad. It's usually bad not because some grammar book says so, but because the preposition is about the weakest type of word short of an article (and you'd never end a sentence on "the" or "a")-- it's actually just a way, usually, of telling the relationship between two things. So whenever you have a sentence that ends on a preposition, see if you can rewrite it to end instead on a power word (those are usually nouns or verbs). And no, I don't mean "up with which" or "from whence" formations. I mean:
He took her to the house he grew up in. (Weak)
He took her to his childhood home. (Strong-- "his" "childhood"-- those come before the power word "home", and they convey emotion (possession and childhood) too .
English sentences are remarkably flexible, first because we have a huge vocabulary (house/home, for example), because our language took words both from the Teutonic and the Romance languages AND we have so many words still extant from the Angles and Saxons, and often two or more of those terms for something still exist in the language. And second, so many words can moved around in a sentence for different meaning-- sentence order is as important as word choice.
So there's always another way to save everything! If a sentence feels awkward or sounds too long or limps to a conclusion or seems vague, you're not stuck with it. There are probably four other ways to say what you mean. So know what you mean, and try to end on a strong word (noun or verb especially), unless, of course, you want to end softly and indeterminately (which you might want to do-- but don't do that just because you didn't revise enough!).
An example-- above, I ended a sentence on "too". This isn't uncommon, but as I did that, I felt it "limp".
Those come before the power word "home", and they convey emotion too.
There's a common synonym for "too," and I'm sure you all know what I mean-- also. But "also" at the end of a sentence is even more lame than "too". "Also" is an adverb ("too" is more complicated-- you can't generally place it as an adverb), and its strongest placement is usually right near the verb. So let's try:
Those come before the power word "home", and they also convey emotion.
See how that "also" not only properly modifies the verb, but also (eek) makes it possible to end on the very strong word "emotion". No limping there!
I can't say it enough. Challenge yourself to write better sentences. Your voice will shine more brightly if your sentences say what you mean in vivid, concrete terms.
