The pessimist looks down and hits his head. The optimist looks up and loses his footing. The realist looks forward and adjusts his path accordingly.
Where the pessimist sees danger hiding behind every back, the optimist sees friendship. Which is why, when we encounter coincidence, we often see conspiracy.
Pessimists outlive optimists.
We have powerful tools: openness, optimism, and the spirit of curiosity. All they have is secrecy and fear. And fear is the great destroyer.[to Rios]
The optimist believes we live in the best of all possible worlds; the pessimist fears this is true.
Pessimism isn’t smarter than optimism. In this life, the bravest thing you can be is optimistic.
Optimism is for a**holes and Earthers.
