You're annoying. If people decide they hate twilight then there'll be a group of mindless followers who begin exaggerating and saying how bad it is. Twilight wasn't that bad, and you know it. She got the story across, and in reality I don't think Stephenie is such a bad author -- it feels like everyone's forgotten what 'story-telling' means; there's a reason why it's not called 'perfect wording'.
You say you're 13, but you seem to have a pretty good grasp of grammar (from your question, a lot of people who ask questions don't even bother to spell them right). If you want to be a writer you have to do it because there's a story you want to tell. It shouldn't matter how well you write, because in time you'll grow and get better -- we all have.
So if you're willing to give up writing just because you think you might write a terrible book then you aren't ready to be an author.
Also you can criticize writers, but avoid saying that someone 'doesn't deserve' to be an author.
1. Carry a notebook, scribble down ideas to use. Avoid starting a new story and save it for later, if its good enough youll still want to write it when your current story is done.
2. READ. Always. It will make writing come naturally and give you a feel for what works and what doesn't.
3. Craft believable characters -- give them habits and tendencies that make them feel real to some extent: your readers will remember them long after they finish the book.
4. Craft a good, believable plot and leave things for the reader to try and find out -- that keeps them reading. Make conflice genuinely engaging, and try to avoid overdramatizing situations. Also try to weave in twists if you see a way to, by leading your readers in one direction and then turning everything around on them.
5. Try and squeeze out some words every day and dont be afraid to make mistakes. Press on toward the end so you dont get stuck in a cycle of self correction.
6. Finally, eat lots of cookies. They taste nice. And for the real final point, try not to compare yourself to other authors. Judge yourself by what you can do, and always strive to write as best as you can. Learn to love writing, and people will love your work -- you wont need to worry about twilight, because her flaws were unbelievable characters and lack of solid plot.
