Your customers buy your confidence first.
Your customers won’t buy from you if you are not quite sold on your offer. Watch your attitude about your product or service.
You cannot hide it.
You will worry about any objection from the prospect if you are not sold on your product or service. Any objection affirms your doubt.
When you are confident about your product or service, you see every objection as an opportunity to educate your prospect. Customers don’t know every benefit your product can offer. You want the objections (I call it customer’s criteria for buying) to come out because you want to help the customer.
Your education of him, your confidence in giving it to him, will help him buy.
Know your product. Have full confidence that it can solve whatever it is meant to solve. Then, sell your confidence.
