The pessimist complains about the wind; the optimist expects it to change; the realist adjusts the sails.
An optimist is a fellow who believes a housefly is looking for a way to get out.
The optimist underestimates how difficult it is to achieve real change, believing that anything is possible and it's possible now. Only by confronting head-on the reality that all progress is going to be obstructed by vested interests and corrupted by human venality can we create realistic programmes that actually have a chance of success.
A lot of people have asked me whether I am a cynic or take a cynical view of politics and are often surprised when I say that I consider myself an optimist, but an optimist dressed in the robes of a realist.
I am a cynical optimist. Big opening weekends are like cotton candy. The films you will remember over time are the films that stick in the consciousness of the audience in a good way.
I'm a technological optimist in that I do believe that technology will provide solutions that will allow the world in 2050 to support 9 billion people at an acceptable standard of living. But I'm a political pessimist in that I am concerned about whether the science will be appropriately applied.
In these times you have to be an optimist to open your eyes when you awake in the morning.
I believe we can prevent or delay most disease until the 9th or 10th decade. The goal is to prevent anything that can affect your quality of life prior to those years! By the time many of us get to the 9th or 10th decade, who knows where the new medical and science will take us? I am an optimist!
Optimism is not inherently a superior way of viewing the world. Certainly doctors will say it might be better for one's physical health to be an optimist. But, morally speaking it may not be appropriate in certain circumstances.
I've always believed my success in the entertainment business is an inevitability. You have to believe that; you have to be an optimist.
