"I am determined to be cheerful and happy in whatever situation I may find myself. For I have learned that the greater part of our misery or unhappiness is determined not by our circumstances but by our disposition."

Abigail Adams: Great necessities call out great virtues.

Abraham Lincoln: Most folks are about as happy as they make up their minds to be.
