Is Adwords Worth It

Is it worth to register for GoogleAdwords to have people see my blog?
As part of my site, I am certain advertising products for different companies, but I do not know if I spend more money than I bring in. GoogleAdwords Has anyone used AdWords? Have you any advice? My blog is wesite: www.nurssage.com
As I have said repeatedly, "People come here for answers," and Google for information and businesses.
