Keep trying—because you're going to hear a lot of "no's," and the key is to get comfortable with rejection. I even have a note taped to my desk that says, "Try to get rejected—to get over the fear of being rejected." As an entrepreneur, especially in the beginning, you'll face resistance and doubt, often from others and sometimes from yourself. But success comes from showing up over and over again, even when it feels like no one believes in you. Persistence is what separates those who make it from those who give up. You only truly fail when you stop trying—so keep going.
