Joe also appeared on the podcast in 2018. Listen to that podcast here. JOE'S TIP: "It took me about six years to become what I would consider to be a sales professional, and another five years to earn what I consider to be a PhD in sales. You might say, where do you get a PhD in sales? Well, you get it in the University of Hard Knocks, and that’s where tuition payments are the commissions lost on deals that you could have won. Here’s my advice. Learn from your mistakes. You mentioned that early on, learning, you’re going to lose deals, you’re going to blow calls, you’re going to mess up. Every time you do that, you’re paying a tuition payment into getting that PhD in sales. But you got to learn from it. You’ve got to incorporate the learnings into the next thing, so the next time instead of spending six months on a deal you’re going to lose, you cut the bait after two months, you disqualify, and you move on to the next deal."
