Style

I found many of these to be helpful when writing my paper, as I am guilty of a few.
#6.  Do not overwrite.
I tend to get carried away at times, especially when writing about a topic I am passionate about.  I babble and carry on jusst when speaking and seem to carry that into my writing style.  I think that one goes hand in hand with #7. Do not overstate.  It's hard to not want to fill in some gaps with slightly more exciting text.
I don't think I'm ever guilty of #14, Avoid fancy words.  Being a brash person myself, I tend to just spit it out without needing to make it sound prettier than it is.
#17 was a good one for me to read as I was going over my papr beause it would have been easy for me to place a lot of my opinion in a paper about my favorite drink...or rather the company that produces my favorite drink.
#20 is kind of the "dah" one.  At this level of writing, no one should be adding foreign languages.
