To succeed in life and in business, you have to be a great salesperson, whether it’s selling yourself, your ideas, or your product.
“Great salespeople are literally the engine of every economy in the world,” says Grant Cardone, a sales expert and the author of “Sell or Be Sold: How to Get Your Way in Business and in Life“. 
So how does one become great? We caught up with Cardone, who shared the 20 qualities that he thinks set great salespeople apart from everyone else.
1. They don’t think in terms of sales but rather in terms of building a business. Great salespeople are working to build a business, not just trying to make a sale. When you think beyond a sale, you get other people’s attention much more easily. They’re going to be more interested in what you have to say, since you want something that’s going to survive beyond one sale.
2. They build their businesses one customer at a time, and always leverage the last customer into more customers. Don’t ever just make a sale and forget about that client. The last sale you make should always open the door to new relationships and clients.
3. They listen more than they speak, getting an understanding of the customer’s needs and then finding a solution. Great salespeople always ask their clients why they want something done. In listening more than talking, you can better accommodate what they are looking for.
4. They deliver more than they promise, and always promise a lot! There’s an old sales mantra that says “under commit and over-deliver,” but Cardone advises that you should “over commit and over-deliver.”
