I always have tons of ideas but i always have to discard them because when i begin to write it i just can't. I know what im going to write but i just can't put it into words. And when i try it comes out sounding choppy.
You should write every day, and it doesn't matter what you put on paper. Keep a journal or just let your thoughts stream out. By doing this every day, you will get in the habit of writing, and also your creativity will increase. In time, your ideas will become easier to put into words. There's a great book called "The Artist's Way," that is especially helpful for writers and anyone who needs help expressing their creativity. There are tons of books on improving your writing style, but the best way is to just write, and maybe get into a writer's group in your area. My group was enormously helpful and supportive. You can do this--happy writing!
