I can never say enough about the power of Jeffrey Gitomer. Besides being the author of The Sales Bible (you should not enter the business world without reading this gem) - I have three copies (one at home, one at the office and one floater to pass along). - he also gives good teleseminar. Tonight was Buying Motives and, as expected, he rocked and rolled my world.
If you're ever feeling like you're in a slump or you need to pick up a new tool or trick I can't recommend a Gitomer teleseminar any stronger. Check him out and get in the game. Otherwise, you'll always be going to "ask your Daddy" (a Gitomerism).
