Hey guys,
In order to really be successful as a hardcore salesperson you must completely understand at both a logical (left brain) and an emotional (right brain) level the product, business and also the psychology of the human species.
The only way to truly achieve these things is to research deeply your topic and then experience it in the real world.
Remember that your clients buy with emotions but justify with logic, they need enough of both in order to see the sale through to the end thereby ensuring your commission gets paid.
Live with passion,
