I like how you mentioned intuition. I was never good at grammar. Remembering the rules seemed like something I couldn't hold on to. I read this one book called, If You Can Talk You Can Write by Joel Saltzman. I bought the book just for the title alone. Makes sense. I just have to write like I talk. It does help to run everything through a text to speech program. After all if a computer can read my words and I can understand it then it must be somewhat OK.
