The optimist proclaims that we live in the best of all possible worlds; and the pessimist fears this is true.

I am an optimist. It does not seem too much use being anything else.

Some people are always grumbling that roses have thorns; I am thankful that thorns have roses.

There are nettles everywhere, But smooth green grasses are more common still. The blue of heaven is larger than the cloud.

Optimism approves of everything, submits to everything, believes everything; it is the virtue above all of the taxpayer.

Optimism, n. The doctrine or belief that everything is beautiful, including what is ugly, everything good, especially the bad, and everything right that is wrong.

The essence of optimism is that it takes no account of the present, but it is a source of inspiration, of vitality and hope where others have resigned; it enables a man to hold his head high, to claim the future for himself and not to abandon it to his enemy.

Children drown, beautiful women are mangled in automobile accidents, cruise ships founder, and men die lingering deaths in mines and submarines, but you will find none of this in my accounts.

Optimism is the content of small men in high places.

Optimism is a kind of heart stimulant-the digitalis of failure.
