I started writing another story yesterday, and my older teenage brother read it. He said it was just like other stories for girls my age. I told him I wanted to write fantasy, but couldn't because of how detailed they have to be! So I asked him if he would help, because he's full of nutty but realistic ideas! He said yes, so I was thinking that he could invent a few ideas and I would come up with a few more and fit them all together. He's a Terry Pratchett nut, so he's got plenty of inspiration! It could be kind of fun! Anyway, is this an ok idea for writing a pretty good book?
