Useless words

I don't remember who first suggested this, but somewhere along the line -- years ago -- I read the suggestion that you can always improve your sentences -- with no change in meaning -- by omitting every instance of the word "very." 

Since then I've never come across a sentence that was better with "very" than without.

This applies to other imprecise adverbs like "extremely" or "quite." 

I wonder what other words are useless.
