Both optimists and pessimists contribute to s.. George Bernard Shaw Quotes
Both optimists and pessimists contribute to society. The optimist invents the airplane, the pessimist the parachute.
@Fokhrul Islam We were taught that pessimists see the glass as half-empty while optimists see it as half-full. Successful living requires a fine balance between optimism and pessimism. Both are feelings of expectations; arising from the state of our mind and depend on the way we experience the forces of faith or fear. Optimism designed a ship to sail daringly into the skies—and fall perhaps at times. So pessimism designed the parachute.
