If the salesman were a true believer in the product, then I could see it working out for them. for example-I could probably be a rep for Sonicare and do very well at it. Having the dental knowledge/vocabulary that I do, and being a true believer in it's benefits-check out this website http://money.cnn.com/2005/03/18/pf/goodlife/inventions/ *ipod? I don't know about that one-maybe it changed the lives of the people who own stock...*
but anyway back to my point-I've never considered sales because I am not interested but I'd sell some Sonicare toothbrushes and change lives.
I don't know how car salesman sleep at night...
