Dominate Your Industry: How to Become the Best in Your Field

"It's not a question of some natural talent or brilliance that you have, it's that you have reached that level of experience or practice," Greene told Entrepreneur.com. "We have to get rid of that old-fashioned notion of genius and creativity."

1. Chose a topic to focus on that you are deeply in love with.
It's the personal commitment to a topic, problem or skill that is ultimately necessary for motivating and maintaining the long hours and fervent curiosity required to rise to the level of "mastery" in a field.

2. Skip all the extra school. Learn by doing.
According to Greene, learning entrepreneurship in school is inane. "Being an entrepreneur is making something, it's like Legos," Greene says and the best way to become an entrepreneur is to try building businesses.

3. Don't focus on making money in your 20s.
"Tune out the idea of making your first million. It's about learning. In the first five to 10 years after college, pursue experience over money.

4. When you have some experience, select a mentor. 

A healthy mentorship relationship is like that between a parent and a child, says Greene. A good mentor should be older than you and at a point in his or her career that he or she is wants to give back. Personality is important, too. "You want somebody who matches your spirit.

5. Be flexible and creative.

Building a company will inevitably confront you with unexpected challenges, and your ability to adjust your path to deal with those surprises is critical.
