Right. Is it just me who has this problem?

I have a very vague storyish idea thing that's been around for about 2 years now. Fine, that's not the problem. However, now when i pick up a new book, whether in a library or shop i want it to be MY story.

Now i seem incapable of really reading anything because i want it to be something else. MY something else.

Is it just me who has this problem and how do i end it?

Probably by actually writing the story. Lol
