One of my mentors says stick at something for 10 years or longer and you'll be the best in your field (not many people last). 

Experts are not lucky. That goes for successful people in any field as well. There are no overnight successes. 

Experts have worked diligently across many hours, days and years to acquire knowledge, skill and experiences that afford them a point of view.  

Stick with it long enough you'll be able to demand what your worth. You'll have an audience to listen. You'll create an impact however wide or small. 

You can predict someone's success by the quantifiable amount of stick-to-it-iveness one can muster in this life.  

Wherever you are headed. Stick to it.
