"What does it take to be a successful entrepreneur? It takes willingness to learn, to be able to focus, to absorb information, and to always realize that business is a 24/7 job where someone is always out there to kick your ass."

It is called working your ass off. The difference is what you are willing to sacrifice. For every writer who wants balance in their life, there is a guy like me who gives up a lot to make their dreams come true. There is always going to be someone out there that knows they have to compensate for maybe having less talent with harder work and preparation.
