Probably when I was 10-11 and wrote the best book ever. I had this creative burst of energy and wrote a story with lots of sex because I thought every book had to have lots of sex in it. I'd say it was 90% sex and 10% story.
It was a pretty stupid story that made no sense, but when I showed it to my parents, they took my computer away. They said I wasn't allowed to use the computer anymore.
I was hoping my parents could give me feedback on the sex part because they had "experience". Well, I couldn't work on the story anymore because they took it away!!!
If you ignore the sex part, it was quite an awesome story at the time. But I guess it was f***ed up because all my characters were 11 year olds (my age) who had sex with each other. Like, one of the scenes was where 2 of the characters had sex on a train while the 3rd one was doing IDK what. (IDK if he was watching or what.)
I literally thought I was going to be a Pulitzer Prize winner.

I had planned everything out... publisher, editor, you name it. I looked it up on the internet. Since Google wasn't popular yet, I used AltaVista.
I also printed out my story and was going to ask my English teacher for advice, but my parents took it away before I could do that.
I know this is going to sound horrible, but I would get 3-4 hours of sleep a night without feeling tired, and I would spend the time drawing "comics" for my book when my parents took it away.

I also made a lot of inappropriate sex jokes to my parents and told them they didn't realize how amazing I was.
