If you are distressed by anything external, the pain is not due to the thing itself but to your own estimate of it; and this you have the power to revoke at any moment.
Confine yourself to the present.
Reject your sense of injury and the injury itself disappears.
[Marcus Aurelius]

As you walk and eat and travel, be where you are. Otherwise you will miss most of your life.
Even as a solid rock is unshaken by the wind, so are the wise unshaken by praise or blame.
Resolutely train yourself to attain peace.
All that we are is the result of what we have thought. The mind is everything. What we think, we become.

The risk of a child born today suffering an early death due to nuclear war is at least 10 percent.

Who needs a corner office when mountains are free?

If the Bible is an ordinary book, and Christ an ordinary man, the history of Christian theology is the story of bookish men parsing a collective delusion. 
[Sam Harris]

War is a racket. It always has been... A few profit - and the many pay. But there is a way to stop it. You can't end it by disarmament conferences. You can't eliminate it by peace parleys at Geneva. Well-meaning but impractical groups can't wipe it out by resolutions. It can be smashed effectively only by taking the profit out of war.
[Major General Smedley Butler]

The nuclear arms race is like two sworn enemies standing waist deep in gasoline, one with three matches, the other with five.

[Top 5 regrets of the dying]

What do you care what other people think?
[Richard Feynman]

I'm simply saying that there is a way to be sane. I'm saying that you can get rid of all this insanity created by the past in you. Just by being a simple witness of your thought processes... It is simply sitting silently, witnessing the thoughts, passing before you. Just witnessing, not interfering not even judging, because the moment you judge you have lost the pure witness. The moment you say “this is good, this is bad,” you have already jumped onto the thought process. It takes a little time to create a gap between the witness and the mind. Once the gap is there, you are in for a great surprise, that you are not the mind, that you are the witness, A watcher. And this process of watching is the very alchemy of real religion. Because as you become more and more deeply rooted in witnessing, thoughts start disappearing. You are, but the mind is utterly empty. That’s the moment of enlightenment. That is the moment that you become for the first time an unconditioned, sane, really free human being.

Climb a mountain, tell no one.

You may be wondering about my credentials to write this book since I am not a doctor—either M.D. or Ph.D. I respond with a story. Penny Simkin, well known educator, writer, speaker, and editor, was called on the carpet by an anesthesiologist, irate that she had written a handout listing the potential trade-offs of epidural anesthesia when she was not a doctor (although he did not dispute her accuracy). "What are your credentials?" he demanded. "I can read," was her reply. So can I. For that matter, you can too.
[Henci Goer]

A human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly. Specialization is for insects.
[Robert A. Heinlein]

The power of accurate observation is often called cynicism by those who have not got it.
[George Bernard Shaw]

Insanity in individuals is something rare – but in groups, parties, nations and epochs, it is the rule.

If you wind up with a boring, miserable life because you listened to your mom, your dad, your teacher, your priest, or some guy on TV telling you how to do your shit, then YOU DESERVE IT.

Committees do harm merely by existing.

The trouble with the world is that the stupid are cocksure and the intelligent full of doubt.

For every 10 people who are clipping at the branches of evil, you’re lucky to find 1 who’s hacking at the roots.

A superior pilot uses his superior judgement to avoid having to exercise his superior skill.

Change breaks the brittle.

The Dalai Lama, when asked what surprised him most about humanity, said: 'Man. Because he sacrifices his health in order to make money. Then he sacrifices money to recuperate his health. And then he is so anxious about the future that he does not enjoy the present; the result being that he does not live in the present or the future; he lives as if he is never going to die, and then dies having never really lived."

Americans spend an average of four hours a day watching TV, an hour of that enduring ads. That adds up to an astounding 10% of total leisure time; at current rates, a typical viewer fritters away three years of his life getting bombarded with commercials.
[Scott Woolley]

The Nazis are regarded as animals in human form because they gassed, shot, or burned perhaps as many as six million Jews. Today the people of the United States are quite prepared, if provoked, to actually burn alive hundreds of millions of innocent men and women, young and old. I deliberately put the matter in such blunt terms because it is long past time to do so and because there is apparently no other way to start people thinking of the moral questions raised by nuclear weapons.
[Steve Allen]

For the love of God, for the love of your children and of the civilization to which you belong, cease this madness. You are mortal men. You are capable of error. You have no right to hold in your hands — there is no one wise enough and strong enough to hold in his hands — destructive power sufficient to put an end to civilized life on a great portion of our planet.
[George F. Kennan]

Modern invention has been a great leveler. A machine may operate far more quickly than a political or economic measure to abolish privilege and wipe out the distinctions of class or finance.
[Ivor Brown]

When schoolchildren start paying union dues, that's when I'll start representing the interests of schoolchildren.
[Albert Shanker, president of the American Federation of Teachers, 1985]

Wherever you go, there you are.
[Jon Kabat-Zinn]

In spite of the unceasing efforts of those who happen to be in authority to conceal this and attribute some other significance to it, authority has always meant for man the cord, the chain with which he is bound and fettered, or the knout with which he is to be flogged, or the ax with which he is to have hands, ears, nose, or head cut off, or at the very least, the threat of these terrors. So it was under Nero and Genghis Khan, and so it is today, even under the most liberal government in the Republics of the United States or of France. If men submit to authority, it is only because they are liable to these punishments in case of non-submission. All state obligations, payment of taxes, fulfillment of state duties, and submission to punishments, exile, fines, etc., to which people appear to submit voluntarily, are always based on bodily violence or the threat of it.
[Leo Tolstoy]

The three most harmful addictions are heroin, carbohydrates, and a monthly salary.
[Nassim Taleb]

There is a huge amount of freedom that comes to you when you take nothing personally.
[Don Miguel Ruiz]

Whenever you find yourself on the side of the majority, it is time to pause and reflect.
[Mark Twain]

This is the real secret of life ― to be completely engaged with what you are doing in the here and now. And instead of calling it work, realize it is play.
[Alan Watts]
