Persevere.........................

Over the endless dark centuries of its evolution, the human nervous system has become so complex that it is now able to affect its own states, making it to a certain extent functionally independent of its genetic blueprint and of the objective environment.  A person can make himself happy, or miserable, regardless of what is actually happening "outside," just by changing the contents of consciousness.  We all know individuals who can transform hopeless situations into challenges to be overcome, just through the force of their personalities.  This ability to persevere despite obstacles and setback is the quality people most admire in others, and justly so;  it is probably the most important trait not only for succeeding in life, but for enjoying it as well.
