For books: realize there are multiple kinds of selling. 1) There's things like used cars. Single, moderate sized transactions, one-time. You want to extract the last dollar, force the close, and generally be like...a used car dealer. I know nothing about this. 2) There's consumer products -- worry about the "funnel", advertising, etc. 3) There's the stuff I like -- high dollar, high-complexity, repeated/ongoing transaction. The best books, hands down, are Neal Rackham's SPIN Selling series: http://www.amazon.com/Neil-Rackham/e/B000APLFJK http://www.amazon.com/Neil-Rackham/e/B000APLFJK
