Difficulties test the courage, patience, perseverance and true character of a human being. Adversity and hardships make a person strong and ready to face the challenges of life with equanimity. There is no doubt that there can be no gain without pain. It is only when one toils and sweats it out that success is nourished and sustained.
Smiling is contagious. We all have our own battles to fight. Each one of us! And sometimes all a person needs is a smile to reassure them that everything will be OKAY (because it will be). Maybe one smile can reassure that girl who sits beside you in the class, that someone sees her - that someone actually cares. Maybe one smile to a stranger you walk by in town today is all it will take to turn that rainy cloud hanging over him into a bright shining sun.
