Please, please, please. Whenever an essay is returned from school, by God, don’t throw it away. You will regret it. Not only for the memories when you read them years later, but you could use them later. It only happened to me once, and that was a novella I wrote for school, that I really want to read… well, about all the time. But I know it can happen to any work you turn in.
If you have a blog or something similar, you can simply upload it there. As I do with both The Hopes Were High, and, for Swedish literature (poetry, novels, novellas etcetera), Nattamat. If you’re Swedish (about six percentages of my readers are), you should upload all school work to the webpage Uppsatslotto, which is an every month lottery giving you an extra ticket to it for every uploaded word.
