The rule of Show, Don't Tell is much like the 180 Degree Rule: it's really important, but not many people follow it.[link]
<-- Here's the 180 Rule by the way.
Now I'm not saying to eliminate words completely, but just shave off any that you don't need, or simply make it so that it really does fit the situation.Extra Info:
More about expositions - Overusing these is like trying to explain a joke to someone who didn't get it. If he didn't get it in the first place, it probably wasn't that good.
The Anime Strategy Syndrome - If you've watched anime, especially something like Yu Gi Oh or Naruto, then you've no doubt seen the characters think out loud with their entire game plan during a tense battle. They talk so much that the action is drowned under exposition. Things like "Ah! You thought I was gonna do this, weren't you? I thought ahead and did that instead. And now you are paralyzed!"
Idiot-Proofing - While you shouldn't assume your audience is a bunch of retards, you should also make everything obvious enough so that even an idiot can understand it. Subtlety is good, but not when no one can even notice it.
Using Compensating as an Excuse - So you can't draw that good. BOO FUCKING HOO. No one gives a shit. Try harder, so you don't have to "compensate" with writing
