Writing

I absolutely adore writing and read everything I can get my hands on. To produce a truly fantastic novel is my ultimate dream, beyond everything else. However... I have absolutely no idea where to start, and I don't really have any ideas. Obviously, this is quite a problem. Music inspires me, food inspires me and people inspire me. But not so much that I want to write a novel based on them/it. I've read books which tell you how to plan, how to write, how to get published... but surely it's not something that you can Really teach? I don't know. I know how to write the news. I know how to engage with online users. But I wouldn't know what to write in a book. And yet I think about writing one everyday! To come home and pick up my laptop and keep typing on my own book would be amazing. If only I could start it! Maybe I should just start writing and see what happens. Any advice?
