“I am an optimist, unrepentant and militant. After all, in order not to be a fool, an optimist must know what a sad place the world can be. It is only the pessimist who finds this out anew every day.”

“The the question whether I am a pessimist or an optimist, I answer that my knowledge is pessimistic, but my willing and hope are optimistic.”

“The world belongs to optimists. Pessimists are only spectators.”

“I'd rather be an optimist and a fool than a pessimist and right.”

“People who are too optimistic seem annoying. This is an unfortunate misinterpretation of what an optimist really is.An optimist is neither naive, nor blind to the facts, nor in denial of grim reality. An optimist believes in the optimal usage of all options available, no matter how limited. As such, an optimist always sees the big picture. How else to keep track of all that’s out there? An optimist is simply a proactive realist.An idealist focuses only on the best aspects of all things (sometimes in detriment to reality); an optimist strives to find an effective solution. A pessimist sees limited or no choices in dark times; an optimist makes choices.When bobbing for apples, an idealist endlessly reaches for the best apple, a pessimist settles for the first one within reach, while an optimist drains the barrel, fishes out all the apples and makes pie.Annoying? Yes. But, oh-so tasty!”

“The man who is a pessimist before 48 knows too much; if he is an optimist after it he knows too little.”
