Very little is needed to make a happy life; it is all within yourself, in your way of thinking.
Marcus Aurelius

We ought to do good to others as simply as a horse runs, or a bee makes honey, or a vine bears grapes season after season without thinking of the grapes it has borne.
Marcus Aurelius

It is no good getting furious if you get stuck. What I do is keep thinking about the problem but work on something else. Sometimes it is years before I see the way forward. In the case of information loss and black holes, it was 29 years.
Stephen Hawking

All political thinking for years past has been vitiated in the same way. People can foresee the future only when it coincides with their own wishes, and the most grossly obvious facts can be ignored when they are unwelcome.
George Orwell

Man is but a reed, the most feeble thing in nature, but he is a thinking reed.
Blaise Pascal

Reading furnishes the mind only with materials of knowledge; it is thinking that makes what we read ours.
John Locke

But perhaps the rest of us could have separate classes in science appreciation, the wonder of science, scientific ways of thinking, and the history of scientific ideas, rather than laboratory experience.
Richard Dawkins

Fame usually comes to those who are thinking about something else.
Oliver Wendell Holmes

I cannot help thinking that the menace of Hell makes as many devils as the severe penal codes of inhuman humanity make villains.
Lord Byron

I don't sit around thinking that I'd like to have another husband; only another man would make me think that way.
Lauren Bacall

A man who as a physical being is always turned toward the outside, thinking that his happiness lies outside him, finally turns inward and discovers that the source is within him.
Soren Kierkegaard

Thinking is more interesting than knowing, but less interesting than looking.
Johann Wolfgang von Goethe

Thinking is easy, acting is difficult, and to put one's thoughts into action is the most difficult thing in the world.
Johann Wolfgang von Goethe

Zen does not confuse spirituality with thinking about God while one is peeling potatoes. Zen spirituality is just to peel the potatoes.
Alan Watts

We don't focus as much in schools on educational knowledge which requires thinking and application, as we do on acquiring facts.
William Glasser

We teach people that they upset themselves. We can't change the past, so we change how people are thinking, feeling and behaving today.
Albert Ellis

When a man asks himself what is meant by action he proves that he isn't a man of action. Action is a lack of balance. In order to act you must be somewhat insane. A reasonably sensible man is satisfied with thinking.
James A. Baldwin

We are a nation that is unenlightened because of religion. I do believe that. I think religion stops people from thinking. I think it justified crazies.
Bill Maher

My thought is me: that is why I cannot stop thinking. I exist because I think I cannot keep from thinking.
Jean-Paul Sartre

All ideologies are idiotic, whether religious or political, for it is conceptual thinking, the conceptual word, which has so unfortunately divided man.
Jiddu Krishnamurti
