“The challenge is to resist circumstances. Any idiot can be happy in a happy place, but moral courage is required to be happy in a hellhole.”

“You can enjoy a deep sense of satisfaction and happiness in life despite challenging circumstances. It's all in how you think about it.”

“Happiness is not a feeling, it is a choice. To be happy, one must choose to be happy, not respond to a circumstance that now controls your happiness.”

“Any intelligent person knows that life is a beautiful thing and that the purpose of life is to be happy," said my father as he watched the three beauties. "But it seems only idiots are ever happy. How can we explain this?”
