A preference to writing

So I have always felt as though I am a really well writer. I've never had too much of a problem with writing essays or responding to any prompts in school unless I know absolutely nothing about the subject; even then I might make something up just so that I don't fail miserably. It might sometimes take me a while to get started with writing but the problem I seem to face often is putting an end to my writing. I am naturally a very talkative person so there isn't really much difference when I go to respond to an assignment that is given. I especially like to do free writes in class because it allows me to get all my thoughts out. I often do this with my journal entries. I'll go to write in my journal one day and end up writing as if I was literally speaking to the journal. I don't think it will be too much of a problem I actually think it is a pretty good problem to have, but I probably could take a chill pill every now and then. I feel like I didn't get that much practice with writing during my senior year. My English teacher didn't challenge us at all they assumed most of us wouldn't want to do the work so they didn't give us any work. I believe I wrote once my senior year and that was a college essay which might I add was pretty darn good in my opinion. It was messed up but I am more than confident that in college I get all the help and practice I will need.
