I hope you can recognize and appreciate the irony of the above quote; it made me laugh. :P Adverbs get a really bad rap among writers...but why? ***
Well, like all writing 'rules', they all started off with good intentions. Try to get through the sentence below, if you can.
Does this sentence make you groan? Then you might understand why the writing 'rule' that says, 'don't use adverbs' may be a good thing. If I replace the adverbs in the above sentence with other words, the sentence becomes much stronger. Watch:
He quickly walked darted up to the curb, then spoke quietly whispered to the man standing there, who was staring at him angrily glaring at him.
Okay, so we all know this isn't the 
most beautiful sentence 
ever, but 
even just replacing those adverbs 
really helped strengthen it, right? There's no need to say "spoke
 quietly" when a better word choice is 
whispered, or 
'stared 
angrily' for 
glared.
But, does this 
really mean we should cut out all adverbs, 
all of the time? Let's take a look at another sentence:
He glanced up from his paper and saw a woman across the street, who was waving to him eagerly.
Now, if we take out that adverb, '
eagerly'...does it 
really improve the sentence? On the contrary, it detracts from the picture. To say she 'waved' doesn't give us a lot of information about what's happening. It could be a 
very bored wave or an angry get-over-here wave or an excited wave, like above. By adding in the '
eagerly', we can see 
more than 
just some woman waving. We see an excited woman waving, and the imagination fills in the rest. Maybe our hero is then confused because he's never seen this woman before in his life, and that, dear reader, could be the beginning of a story. :)
The problem is--as with most writing 'rules'--that people seem to take all this advice as 
law. Doing so is like having a toolbox, but saying you will 
never use a hammer again because it didn't work right on one project, so it's a bad tool. This isn't true! A writer's toolbox should be 
filled with 
even the 
most 'mundane' or 'cliche' tools, because 
even those are important sometimes. Adverbs are 
not a waste of space; they 
just need to be used 
wisely.
A good rule of thumb (and again, not 
law) is to examine all your adverbs (and every other word, for that matter!) for usefulness. 
As I mentioned in a previous post, verbs are one of the strongest words you can use, so if you can replace 'he walked 
slowly' with 'he ambled' or 'he tiptoed', 
most likely that will be the better choice. Again, you may find times that this doesn't work for whatever reason--that's fine! Adverbs are 
not just a waste of space (why do you think we have them???) and should be used like any other tool in the writer's toolbox: with care and precision.
And sometimes, your sentences
 just need to 
flow, and if the word choice doesn't work for that, well, change it! You can't have 
every sentence say "He ambled. He glared. He strode." or else 
that would get 
very boring 
quickly, 
too. The secret to great writing is 
variation and 
moderation, as you will learn in the upcoming weeks.

To illustrate a point, I underlined all the adverbs in this post (that I caught. I might have missed some, haha.) Quite a few, huh? And I wasn't even trying! But as you can see, if I removed all my adverbs...this post would be pretty boring. Adverbs have their place in the world, like anything else--we just need to learn to use them properly
