One of the hardest thing to do in writing, for me at least, is cutting down on unnecessary words. But having a trimmed manuscript is essential to going far as an author.
WELL, I found this AWESOME, AWESOME, AWESOME link with AWESOME ideas on how to cut thousands of words from your manuscript. (How many words would you cut from that sentence?) :)
HERE IS THE LINK
Here's ANOTHER LINK that is only slightly different. You decide which is best for you. I use both.
They both give words you can find (ctrl + F) and ponder if they're really necessary. They can be used, just not in overabundance. :)
So if you need to tighten your manuscript, whether you're an author trying to get published or a student writing a paper, give the link a look-see. I promise you won't regret it.
