This famous quote hangs over my desk, as well as the desks of many people with the hubris and optimism to believe they can change the world for the better. It seems implausible, yet time and again history has proven it true. Virtually every major shift in cultural history can trace its origins to the work of a small group, often gathered around an innovative thinker or body of thought.

It is important to possess a short-term pessimism and a long-term optimism.

No person ever ended his eyesight by looking on the bright side.

Surround yourself with optimistic people.

You need a mind open to possibility, conditioned to love the creative spirit we all have inside ourselves.

And wisdom is a butterfly And not a gloomy bird of prey....

If pessimism is despair, optimism is cowardice and stupidity. Is there any need to choose between them?

Optimism is a seed sown in the soil of faith; pessimism is a seed hoarded in the vault of doubt.

May the optimism of tomorrow be your foundation for today.

If you don't have any money, it is still a simple process to create in your feelings an acknowledgement that what you do have is abundance and the world is, in fact an abundant place to be.
