Success lies in perseverance, and excellence lies in specialization. If a salesperson cannot close a deal, all product knowledge and sales skills are meaningless. Without a sale, there is no salesmanship; it is as simple as that. When visiting clients, a salesperson should follow the principle: "Even if you fall, grab a handful of sand." This means a salesperson should never return empty-handed; even if a sale is not made, they should strive to have the client introduce a new prospect. The Self-Image: One of the greatest discoveries is that through continuous imagination, one can become the person they aspire to be. You must imagine yourself as a successful, wealthy, positive, passionate, and highly motivated individual. Dedicate time each day to envisioning your success, rather than imagining yourself as a born loser. Without health, having many chess pieces still results in a loss; without health, no amount of wealth can bring happiness. For gamblers who treat life as a gamble, when they dare to act recklessly, they possess full confidence in their own strength and believe that bold adventure is the only way of life.
