I've read more than a few writing books by famous writers. Stephen King's book On Writing resonated with me the most. It could be because I grew up with Stephen King. Well, Nancy Drew, The Girl with the Silver Eyes and Stephen King. That's what I remember from my childhood as far as books. Oh and the Giving Tree. That book made me cry, and it wasn't until I got a little older that I understood why.
That sounded harsh to me at first, but I think it's meant to. If you want to be taken seriously as a writer, if you want to be a writer who publishes stories or books or poems, you have to sit down and write even when you don't feel inspired. There are many days I don't feel like writing. Everything that gets slapped onto the page looks like it's been slapped onto the page. I trudge forward regardless. I can edit later, but only if there are words there to edit. Can't edit a blank page. So, there has to be something there. Anything.
"I have spent a good many years since - too many, I think - being ashamed about what I write. I think I was forty before I realized that almost every writer of fiction or poetry who has ever published a line has been accused by someone of wasting his or her God-given talent. If you write (or paint or dance or sculpt or sing, I suppose) someone will try to make you feel lousy about it, that's all." -Stephen King
If Stephen King could go through most of his life being ashamed of his books and his writing, yet be so prolific and write huge volumes that could scare us to death, then it's okay if I feel like my stuff is crap most days.
I'll just get up and go to work.
