An optimist is a person who sees a green light everywhere, while a pessimist sees only the red stoplight. . . The truly wise person is colorblind.
Albert Schweitzer quotes
Perpetual optimism is a force multiplier.
Colin Powell quotes
I don't know. People always think that there has got to be a dark side to everyone, a closet with skeletons, demons under the bed. People think all kinds of things about one another. They feel compelled to make up fears and false assumptions about their closest friends. Truth is, I'll never know all there is to know about you just as you will never know all there is to know about me. Humans are by nature too complicated to be understood fully. So, we can choose either to approach our fellow human beings with suspicion or to approach them with an open mind, a dash of optimism and a great deal of candour.
Tom Hanks quotes
Optimism: The doctrine that everything is beautiful, including what is ugly, everything good, especially the bad, and everything right that is wrong. ... It is hereditary, but fortunately not contagious.
Ambrose Bierce quotes
Great leaders are pragmatists who can deal with difficult realities but still have the optimism and courage to act.
Nitin Nohria quotes
A pessimist sees the difficulty in every opportunity; an optimist sees the opportunity in every difficulty.
Winston Churchill quotes
In these times you have to be an optimist to open yours eyes in the morning.
Carl Sandburg quotes
Optimism is the faith that leads to achievement. Nothing can be done without hope and confidence.
Helen Keller quotes
Don't ever become a pessimist, Ira; a pessimist is correct oftener than an optimist, but an optimist has more fun--and neither can stop the march of events.
Robert A. Heinlein quotes
The optimist proclaims that we live in the best of all possible worlds; and the pessimist fears this is true.
James Branch Cabell quotes
