Here are my gentle 5-cents-worth of advice:
Make your title and description more descriptive. (Do NOT change the URL, however!)
When people find your listing on the Google search results pages, they see nothing but a big fat "Life's a curve...", and in the description underneath: "...a learning curve".
How do they know what your page is about?
Why would they click on such meager information?
Title and description are our most important tools to get click-throughs to our articles. Make them informative, persuasive, attractive. attention-grabbing...whatever it takes.
Good luck with your books, Rob. They look very interesting.
