Another one in the hall of "writers who don't read their own articles," this was the sentence preceding the one about the wage gap.
I worked in sales for a decade. I was better than top 1% at it nationwide. I'm 6'4". Was that because people just love buying from a tall person, or was it because I felt comfortable walking up to anyone and everyone since I was taller than them?
FWIW, I have known a lot of people in sales and it's not confidence that makes you good - that's just a stereotype - but the ability to make the other person feel like you have their interest in mind. Sure you have to be willing to approach someone but without the ability to establish a connection, the confidence would be misplaced. It also seems like anyone can train themselves out of cold call anxiety.
