While you were sleeping

Apparently there's been a run on self-help tapes that you listen to in your sleep.

The products with perhaps the broadest potential market, and often the most extravagant promises, are designed for so-called sleep learning. Professionals who think the boss has been a little slow with that promotion — and who have left their skepticism in their other briefcase — can try to kick-start their careers with the Wealth & Success Power Affirmations subliminal program (“start advertising to your own mind”). Sold through sleeplearning.com, it can be played through stereo pillow speakers available on the same Web site for $29.95.

Me, I'll stick to the tried and true method for achieving success: Sleeping with a copy of How to Win Friends and Influence People under my pillow.
