Don't Beg From Your Customers, Either

Most customers will buy from people they respect and believe in to solve their problems. Rarely will they buy from you if they feel sorry for you and know that you need the business.

I learned a good saying from a friend many years ago that definitely helps: "I don't need to do business with you. But I would like to do business with you, and you can be assured I will do my very best to deliver on what we agreed on."

Don't Remember Anything About Your Customers

This piece of advice may seem counterintuitive but it makes real sense. If you can remember everything about your customers, then I think you aren't serving enough customers and giving your business even more room to grow.
