I'm totally the opposite. If I really like a story I am so in that universe I can produce stories people say could have been published with the original (which is probably a compliment higher than merited.)

But I can't write my own world well and I get major intimidation issues even with writing the story on a computer. It's really sad because I just want to finish my story ideas, lol. I HAVEN'T BEEN ABLE TO SUCCESSFULLY DO THIS ONCE SINCE HIGH SCHOOL.
