Customers don't measure you on how hard you tried, they measure you on what you deliver.
Your customers don't care about you. They don't care about your product or service. They care about themselves, their dreams, their goals. Now, they will care much more if you help them reach their goals, and to do that, you must understand their goals, as well as their needs and deepest desires ...
Get closer than ever to your customers. So close that you tell them what they need well before they realize it themselves.
