PLEASE HELP CONTINUE WITH PREFACE?

what should i write after....."The past three years, my life in Middle School has gone from being a nervous 6th grader to an accomplished 8th grade writer. As a 6th grader, I didn’t realize how much more there was to learn about writing until the end of 6th grade. I thought you’d just take a pencil and write words. But writing is much more than that." .....What else should I write???
