awww.... I'm sure though you can write since you love to read and have a great imagination. We are, after all, our worst critics. Maybe if you are really wanting to, there could be some classes to take on it. But I'm sure you could knock out something fantastic if you started writing and just didn't think about it.
I don't really have a reason to, I just wish I could sometimes. I can never seem to put what I'm thinking into words on paper. There was only one time that I wrote anything good, and I was really emotionally charged at the time...lol!
