Why is the approach a critical part of the sales person?
The "approach" in a sales pitch is VERY crucial to making a sale.
Think of it like this: Someone approaches you and says "HEY HEY HEY BUY THIS!" Most people are unlikely to want to buy.


Additionally, If someone lacks confidence and whispers their sales pitch, that won't get many customers either.

A good "approach" makes the consumer feel the salesperson is trustworthy and is coming from a position of trying to be helpful.
