“People who perceive the negative experiences in their lives as the result of uncontrollable forces are at a higher risk for depression than those who believe they have control”

“Those who put more effort into keep­ing negatives out of mind end up being more depressed than those who do not.”

“Take control of your destiny. Believe in yourself. Ignore those who try to discourage you. Avoid negative sources, people, places, things and habits. Don't give up and don't give in.”

“There are people who cannot risk loneliness with the experience. They always have to be in a flock and have human contact.”

“The human race divides politically into those who want people to be controlled and those who have no such desire.”

“However, robust evidence shows that people systematically overestimate the probability of positive future contingencies, and underestimate the probability of negative ones — only those who are depressed or dysphoric come to accurate assessments.”
