Successful Entrepreneurs Have Passion and Motivation

Although there are many traits that make an entrepreneur successful, perhaps the most important are passion and motivation.
Is there something you can work on over and over again without getting bored?
Is there something that keeps you awake at night because you haven't finished it yet?
Is there something you have built and want to continue to improve upon?
Is there something you enjoy so much you want to continue doing it for the rest of your life?
From building and implementing a prototype to pitching your idea to venture capitalists, success is a function of passion and determination.
