Sales empathy is the ability to understand why the customer thinks the way he thinks and feels the way he feels. Obviously, a salesperson can think and feel differently. However, you absolutely must have the ability to get out of your mind and put yourself in the customer's shoes, as well as understand the general context.
Both on a personal and professional level, it is very important to generate empathy, even more so if we are in a commercial environment. Nowadays, there are still suppliers with a traditional business mindset: this means that they try to sell the same thing to everyone, without taking the time to empathize with that customer. Also, you should keep in mind that there are tools that can help you develop a better strategy along with the empathy present in social networks.
