Think about your customers, current or potential. Describe them, their need, hopes, fears, and pains. Everything you can. Listen to them to get this information. Listen, do not talk that much. Are you trustworthy? The way you behave, what competitors tell him about you, and everything he’s able to know will determine. If the answer is no, you are in trouble. If it is yes, can you make him be better? After that, everything else will come. Good luck. But lots of effort.
