Answer:
Although this year has had its downsides, I can look back upon it fondly. I have learned important lessons on making sure to hand in my work on time, and prioritizing myself. Unfortunately I have fallen out of touch with some people I have cared deeply about it in the past, but I only hope to either regain their friendship or build new ones. Next year holds an attractive mysteriousness; I am excited to figure out what new and exciting things I can learn about next year.
