I'm 18. I constantly find crap in my work, for it is not hard to find.
Get yourself motivated by watching interviews with authors, or reading, or listening to podcasts about it. When you're finished with that, which might be very unlikely, come into this forum and just spill out your doubts. Not just your work.
Writing a novel isn't writing a letter. It takes more than one day. It takes more than one go.
You're 17! Just be glad you're into writing when most people you're age do pretty much nothing but...you know what.
My God! me at 17, and this was just a year ago, almost, I've learned so much!
Acknowledge that you're a dynamic, changing mind. Allow it to KNOW that you're gonna have more stuff in your mind, more knowledge, more ideas, more talks, more introspective narrative, that you're gonna be able to create conflicts and dialogs better than you currently do.
Read books. Books that you think a story of yours could contain.
There's so many people out there who write and then give up for some reason.
Just think to yourself, that you might actually be one of those that gets to put a story on the shelves to entertain and enlighten people.
Some people might even give up becaue they have the impression that writing a novel is like writing a letter. And you make no big corrections. This is because they read the book and it flows. "OOO, I wish I could write like that. If it all just came to me like that. If it flwoed."
You'd be surprised how much editing goes on in "great books".
J.K.Rowling took a year, usually to write a book. And then it could be read, by some, in less than 24 hours.
A good author is one who fools people into thinking that he can write nonstop, I would guess. Where you find no gaps.
Soldier on, like you said. You're not alone in trying to be a writer.
It's no piece of cake, as I've realized. But that makes me laugh and think 'So what?'
And then I just soldier on for more stupid ideas and stuff I won't even use for my story and dialog that will make me fall to my knees surrounded by slow-motion falling Autumn leaves because of how horrible the writing is.
Again, you're 17. Aknowledge that. You shouldn't expect so much of yourself.
Realise that it's ok to put excremental prose on paper when you're young. That's how we come.
At least that's how I came. And I don't give a s**t about other people.
