Selling 101

I am trying to bring a new sales person up to speed on sales techniques.  What I am finding are vast disparities about how to sell?  I have been selling for more than 25 years now and I believe the key to selling is being honest and conveying your genuine interest in the other person. If they are having an issue,  help resolve it, if its a pricing questions help answer it.  This is something that can be done effectively over the phone. The sentiment comes through if you are honest .  I hear it in the voices of customer service people I deal with daily.  With all the tools and tricks that we supposedly have to the Art of selling it really is just Listening and being there to help.
