Entrepreneurship is a gamble. And with the chips stacked against you, it's difficult to know whether an idea has possibilities. I've taken the leap four times, each time just as much of a roller coaster as the last. These experiences have taught me a valuable lesson: It's not just about finding a good idea; it's finding an idea worth pursuing.
But, finding that idea, and building a company with that idea in mind, is always a struggle. It almost has to be that way.
