Know When to Shut Up

I like people who don't require a lot of chitchat. What's great about Wall Street guys (and there's a lot of negatives, too) is they're tuned in to the notion of, "I just need to know what I need to know and I don't need to know any other information." They can sense right away if it's time to get off the phone – and those are great attributes because everything else is just wasted time.
