Uncomfortable lessons

So the feedback on my last assignment has brought home some uncomfortable truths.

1. Sometimes I try to cut corners with my references.  I skim thru looking for only what I want, then put them in as a quote, when in fact if I read the whole article, it may not be what the author was going on about at all!
2. I have to watch how I insert a reference into my writing.  Sometimes the way I do it can imply that the author has read my assignment and lent their support, when in fact all I'm using is their idea.  It's an easy fix - instead of say "blah blah blah author's idea (author 2009)", I need to do something like:"Author (2009) says blah blah blah"
3. Apparently I end my sentences with prepositions a lot.  Admittedly I then had to go onto Google and find out what a preposition was.  Love to know how i got thru 2 degrees and a diploma without that being picked up before!
4. Same with split infinitives.  "To boldly go" is apparently wrong.  "To go boldy" is apparently correct.  Whatever.  I still want to boldy go. 

I guess learning can't be comfortable all the time.
