Know-How Exchange : Website Critique

I'm not getting the sign ups to my mailing list that I had hoped for. I'm an writer who created the site to market my book, A Patchwork of Comforts. Every two weeks I send out a short paragraph on simple ways to de-stress and get more pleasure out of life. I get action on the site, but few sign-ups. I need feedback about my site. Is there something wrong with the way I present it?
