An obsession towards something will beat talent everyday. So become obsessed. Let whatever you love completely consume your life. Do it for the greater good.
I always wondered how successful people were able to achieve these things that most would consider crazy and impossible.
For one it was very clear that they kept their focus towards whatever it is that they set out to do in a consistent manner.
They let their goals, their visions completely consume their lives.
Michael Jordan didn't make his schools basketball team because he was deemed too short to play at that level. Did that stop him?
Walt Disney filed for bankruptcy several times because he was unable to pay his bills or his employees. Did that stop him?
Robert Downey Jr. was arrested several times for drug use/distribution and possession of an illegal gun. Did he keep going?
Oprah Winfrey was fired from her news reporting job because she was "unfit for television news". Did that stop her?
When you read enough of these stories. You realize that greatness doesn't take incredible skill or talent. Instead it requires you to believe in yourself and never give up on your vision.
If you're persistent...you will eventually find a way in.
