I am a salesman. Why do I suddenly feel blank when I talk to clients?

Because I care too much about the result.

Change your mind.

Sales is not to let others buy their own products, but a win-win process.

Doing sales is to introduce your product to customers who really need it. Customers will be happy if they really need it.

If a sale is unsuccessful, don't attribute it too much to the inside. It's not just about your own products and capabilities. More than that, this customer has no such demand at present.

Think like this, put aside the idea that sales are begging for help, take sales as the starting point to recommend good things to the right people, put down the burden in your heart and go into battle lightly.
