People often live with the brow of an optimist above and the jaw of a pessimist below. To make one dominate another is to create real value in life. A positive approach to everything one does helps to build a skill set that makes a smile last a lifetime. Whereas, one sardonic smile can bring gloom that blankets everything around.
The life with no challenges is fatal to a striving for the better human nature. It should be like the turbulent see that hurries you along. Sometimes lands gently, occasionally, dashes you on a beautiful coast or a piece of a rock. And the force of this fall may determine your future success in life.
