“No pessimist ever discovered the secret of the stars or sailed an uncharted land, or opened a new doorway for the human spirit.” – Helen Keller
Pessimists are by nature doubtful and suspicious of the unknown. Optimists, on the other hand, tend to be trusting, often to a degree not warranted by the factors at hand. To be a pessimist, one has to have given up on the promise of life at a certain level. Conversely, to be an optimist, one tends to leave room for the promise of life, no matter how grim the circumstances.
For myself I am an optimist – otherwise I would be forced to mope when the clouds of trouble and distress gathered in the skies above me. Sulking never lightens the burden of difficulty. Likewise, despondency blinds one to the opportunities present in distress. There is no help for the hopeless!
