One of the hardest lessons to learn, and in entrepreneurship or innovation, is realizing that nobody cares about you or your product. The only way that you know if they actually care is when they purchase some thing. It is the purchase decision that reveals their interest in what you’re doing.It reveals a lot about who people are and what they actually say. Once you realize this, you make many different decisions in your life. You become a lot more independent, and you stop listening to what other people are saying, until they actually perform an action.
