Being in control of your own personal destiny is one of life's greatest challenges and also rewards. Being an entrepreneur you need to absolutely realize that it is YOU and only YOU who can transform your vision into a reality. While most people choose to seek structure and security in their careers, entrepreneurs trade structure and security for the chance to live the true “American Dream”.
At the end of the day you will only have significant success when you're borderline obsessed with your goals. Remember that every big shot was once a small shot that kept shooting!
