Confidence is key.
Confidence is the key to success in any sales business. Never arrogance. Confidence can only come from knowing yourself, your direction, your product, and your ability to help in the given situation. It is my opinion, that until you are 100% sure you have what the client needs, you will not exhibit the level of confidence the other party needs to hire you. So, the best you can do for any client is to make sure you are the right match for them. That there needs align with your strengths. The only way to do that is to ask the right questions and not compromise your answers. You don’t need every client. Your business will grow when your caliber of client does. And your business will grow when you grow, it’s hard and prosperous work.–NK
