Without courage we cannot practice any other virtue with consistency. We can't be kind, true, merciful, generous, or honest. — Maya Angelou

Everyone has an invisible sign hanging from their neck saying, ‘Make me feel important.’ Never forget that message when working with people. - Mary Kay Ash

The main tool for the acquisition of wealth and power is knowledge and self-discipline. - Arthur Ashe

Routine, in an intelligent man, is a sign of ambition. - W.H. Auden

The proper, wise balancing of one's whole life may depend on a cup of tea at an unusual hour. - Arnold Bennett

To exist is to change, to change is to mature, to mature is to go on creating oneself endlessly. - Henri Bergson

To have positive liberty, he explained, is to take control of one’s own mind; to be liberated from irrational fears and beliefs, from addictions, superstitions and all other forms of self-coercion. - Isaiah Berlin

C

So often, when you see someone who’s really good at almost anything, it’s because they actually started out exactly the opposite — and then they cared so much about fixing that problem. - Susan Cain

A man is about as big as the things that make him angry. ― Winston Churchill

Happiness, in fact, is a condition that must be prepared for, cultivated, and defended privately by each person... People who learn to control inner experience will be able to determine the quality of their lives, which is as close as any of us can come to being happy. - Csikszentmihalyi, Mihaly

The ability to show up everyday, stick to the schedule, and do the work — especially when you don't feel like it — is so valuable that it is literally all you need to become better 99% of the time. - James Clear

D

Each man's death diminishes me, For I am involved in mankind. Therefore, send not to know For whom the bell tolls, It tolls for thee. - John Donne

If you can't measure it, you can't improve it. - Peter Drucker

We are what we repeatedly do. Excellence then, is not an act, but a habit. - Will Durant

E

What do we live for, if not to make life less difficult for each other? - George Eliot

If you wish to improve, be content to appear clueless or stupid in extraneous matters. - Epictetus

If I had an hour to solve a problem I'd spend 55 minutes thinking about the problem and five minutes thinking about solutions. - Albert Einstein

A foolish consistency is the hobgoblin of little minds. - Ralph Waldo Emerson

Notes aren’t a record of my thinking process. They are my thinking process. – Richard Feynman

The first principle is that you must not fool yourself – and you are the easiest person to fool. - Richard Feynman

Ultimately, man should not ask what the meaning of his life is, but rather must recognize that it is he who is asked. In a word, each man is questioned by life; and he can only answer to life by answering for his own life; to life he can only respond by being responsible. ― Viktor E. Frankl

It is easier to act yourself into a new way of thinking, than it is to think yourself into a new way of acting. - Millard Fuller

Don't aim at success. The more you aim at it and make it a target, the more you are going to miss it. For success, like happiness, cannot be pursued; it must ensue, and it only does so as the unintended side effect of one's personal dedication to a cause greater than oneself or as the by-product of one's surrender to a person other than oneself. Happiness must happen, and the same holds for success: you have to let it happen by not caring about it. I want you to listen to what your conscience commands you to do and go on to carry it out to the best of your knowledge. Then you will live to see that in the long-run—in the long-run, I say!—success will follow you precisely because you had forgotten to think about it ― Viktor E. Frankl

Your audacious life goals are fabulous. We're proud of you for having them. But it's possible that those goals are designed to distract you from the thing that's really frightening you—the shift in daily habits that would mean a re–invention of how you see yourself. - Seth Godin

One sense of normal is statistically normal: what everyone else does. The other is the sense we mean when we talk about the normal operating range of a piece of machinery: what works best. These two senses are already quite far apart. Already someone trying to live well would seem eccentrically abstemious in most of the US. That phenomenon is only going to become more pronounced. You can probably take it as a rule of thumb from now on that if people don't think you're weird, you're living badly. - Paul Graham

H

If I am not for myself, who will be for me? But if I am only for myself, who am I? If not now, when? - Rabbi Hillel

"The world breaks everyone and afterward many are strong at the broken places. But those that will not break it kills. It kills the very good and the very gentle and the very brave impartially. If you are none of these you can be sure it will kill you too but there will be no special hurry." - Earnest Hemingway, A Farewell to Arms

The years go fast. Do everything you can while you can. - Beverly Johnson

Until you make the unconscious conscious, it will direct your life and you will call it fate. ~ Carl Jung

K

When you can measure what you are speaking about, and express it in numbers, you know something about it, when you cannot express it in numbers, your knowledge is of a meager and unsatisfactory kind; it may be the beginning of knowledge, but you have scarcely, in your thoughts advanced to the stage of science. - Lord Kelvin

L

It has been my experience that folks who have no vices have very few virtues. - Abraham Lincoln

The foundation of productivity is habits. The more you do automatically, the more you’re subsequently freed to do. This effect compounds. - @mmay3r on twitter

I have known no wise people who didn’t read all the time—none, zero,” Mr. Munger once said. “You’d be amazed at how much Warren reads—and at how much I read. My children laugh at me. They think I’m a book with a couple of legs sticking out. - Charlie Munger

Exercise turns out to be the closest thing to a wonder drug that self-control scientists have discovered. For starters, the willpower benefits of exercise are immediate. Fifteen minutes on a treadmill reduces cravings, as seen when researchers try to tempt dieters with chocolate and smokers with cigarettes. The long-term effects of exercise are even more impressive. It not only relieves ordinary, everyday stress, but it’s as powerful an antidepressant as Prozac. Working out also enhances the biology of self-control by increasing baseline heart rate variability and training the brain. When neuroscientists have peered inside the brains of new exercisers, they have seen increases in both gray matter—brain cells—and white matter, the insulation on brain cells that helps them communicate quickly and efficiently with each other. Physical exercise—like meditation—makes your brain bigger and faster, and the prefrontal cortex shows the largest training effect. - Kelly McGonigal

Here is my secret. It is very simple: it is only with the heart that one can see rightly. What is essential is invisible to the eye. — Antoine de Saint Exupéry

The reasonable man adapts himself to the world: the unreasonable one persists in trying to adapt the world to himself. Therefore all progress depends on the unreasonable man. - George Bernard Shaw

Being poor is not having too little, it is wanting more. - Seneca

Life can be much broader, once you discover one simple fact, and that is that everything around you that you call ‘life’ was made up by people that were no smarter than you. And you can change it, you can influence it, you can build your own things that other people can use. Once you learn that, you’ll never be the same again. - Derek Sivers

What information consumes is rather obvious... it consumes the attention of its recipients. Hence a wealth of information creates a poverty of attention, and a need to allocate that attention efficiently among the overabundance of information sources that might consume it. - Herbert Simon

No person would give up even an inch of their estate, and the slightest dispute with a neighbor can mean hell to pay; yet we easily let others encroach on our lives—worse, we often pave the way for those who will take it over. No person hands out their money to passersby, but to how many do each of us hand out our lives! We’re tight-fisted with property and money, yet think too little of wasting time, the one thing about which we should all be the toughest misers. - Seneca

The best programmers are not marginally better than merely good ones...They are an order-of-magnitude better, measured by whatever standard: conceptual creativity, speed, ingenuity of design, or problem-solving ability. — Randall E. Stross

Part of my joy in learning is that it puts me in a position to teach; nothing, however outstanding and however helpful, will ever give me any pleasure if the knowledge is for my benefit alone. ~ Seneca

I gave a commencement speech in Minnesota few years ago [at the Carlson School of Management]. The core of it was to be your unapologetically weird self. I think authenticity is one of the most lacking things out there these days.” An excerpt from that speech: “Weirdness is why we adore our friends. . . . Weirdness is what bonds us to our colleagues. Weirdness is what sets us apart, gets us hired. Be your unapologetically weird self. In fact, being weird may even find you the ultimate happiness. - Derek Sivers

The key to life is doing the things that no one else wants to do. - Zoe Schwartz
