I guess what I learned about my thinking is that it lacks a lot of focus. I found myself wandering a lot throughout the essay, wanting to go towards completely different points or pieces of evidence. It took me a lot longer to write the essay than I wanted it to.
Other than the focus problem, I realized I don't like exact quotes. I'd rather refer to a whole passage than try to narrow it down to one single quote. I have trouble putting a whole point into one short line, and that's something to work on. I think I did alright picking quotes, but I'd like to get better at it.
As far as the focus goes, it's probably an ongoing battle that a lot of people face. Maybe thesis-evidence essays bore me, and I have trouble with the attention span required to write them. This could mean that I'm better at writing things I'm really interested in. Unfortunately, for the rest of my years in school, I'm going to have to write about a lot of stuff that I don't care for. This means it's something to look at and try to find patterns about.
In conclusion, there are two things I really need to work on- focusing on single ideas and formulating points into compact statements. Both of these involve a little more determination in writing, and I'll certainly think about it.
