Entrepreneurs are famously optimistic. They are endowed with a bias toward optimism, according to research by Penn State University. This tends to be doubly true for serial entrepreneurs, who look at each time at bat as an opportunity to hit a home run.
Entrepreneurs often have the mentality, "If you build it, they will come." And often they are disappointed. Just because you launch a company, you can't expect clients to be knocking down your door, begging to sign up for your service or buy your product. Building a company and generating revenue takes time. I advise new entrepreneurs that it often takes several months -- if not longer -- to win that critical first client.
