Workers of the world, meet Kerry Hannon, from now on known as your new best friend. Her latest book, Love Your Job: The New Rules for Career Happiness, (Wiley/AARP, 183 pages, $19.95) takes a solid and realistic approach to getting the most out of your current job, rather than complaining, quitting (though she acknowledges that sometimes this is an appropriate option) or quietly dying a thousand deaths. Your dream job could be, with the right thought and effort, the one you already have.
