"Urgent optimism is the desire to act immediately to tackle an obstacle combined with the belief that we have a reasonable hope of success." Jane McGonigal #optimism
"It is the hopeful, buoyant, cheerful attitude that wins. Optimism is a success builder; pessimism an achievement killer." Orison Swett Marden #optimism
"The essence of optimism is that it takes no account of the present, but 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." Dietrich Bonhoeffer #optimism
"Hope definitively isn't the same thing as optimism. Hope is not the conviction that something will turn out well but the certainty that something makes sense, regardless of how it turns out." Václav Havel #optimism
