Marketing. How?

I love to write. I could do it all day, every day.

I dislike trying to sell my book. I'm naturally shy and most of the many marketing tips I've read don't seem to suit my personality.

But I want people to read my books. I hope they'll actually benefit from my stories, just as I've benefited from most of the thousands of books I've read.

So what's the solution?

How do you go about marketing your books?
