“Optimists are happier in life for a reason.”

“Only optimists commit suicide, optimists who no longer succeed at being optimists. The others, having no reason to live, why would they have any to die?”

“One reason that cats are happier than people is that they have no newspapers.”

“In life, if you want to be happy, choose to be optimistic.”

“Forgive and forget, but never forget to forgive. You may find a happier heart is the key to a happier life.”

“For optimists, human life never needs justification, no matter how much hurt piles up, because they can always tell themselves that things will get better. For pessimists, there is no amount of happiness—should such a thing as happiness even obtain for human beings except as a misconception—that can compensate us for life’s hurt. As a worst-case example, a pessimist might refer to the hurt caused by some natural or human-made cataclysm. To adduce a hedonic counterpart to the horrors that attach to such cataclysms would require a degree of ingenuity from an optimist, but it could be done. And the reason it could be done, the reason for the eternal stalemate between optimists and pessimists, is that no possible formula can be established to measure proportions and types of hurt and happiness in the world. If such a formula could be established, then either pessimists or optimists would have to give in to their adversaries.”
