Those who try harder get more done.

Tenacity is one of the most important traits of successful people.
Lesser people give up. When things get difficult and they don’t know what to do, some people stop trying. They seek a simpler, easier goal.
The world is full of challenges and some of them are indeed quite hard. Only those who are truly committed to success will keep going. They never give up. Sure, some people have innate talents and abilities. Some may have initial advantages. But because most people lack the tenacity to keep going, the driven individual can learn more, get more done.
When you’re choosing your personal values, tenacity is a great one.
