Perservere through the tough times.

If you want to go fast, go alone. If you want to go far, go together.

Not everything that can be counted counts, and not everything that counts can be counted.

Facts do not cease to exist because they are ignored.

How we spend our days is, of course, how we spend our lives.

It is the mark of an educated mind to be able to entertain a thought without accepting it.

Sometimes people use "respect" to mean "treating someone like a person" and sometimes they use "respect" to mean "treating someone like an authority" and sometimes people who are used to being treated like an authority say "if you won’t respect me I won’t respect you" and they mean "if you won’t treat me like an authority I won’t treat you like a person" and they think they’re being fair but they aren’t, and it’s not okay.

If adventure is about anything, it's about finding a newer version of yourself in hard-to-reach places.

I wrote a long letter because I didn’t have time to write a short one.

What do you want it for? What do you want the audience for?

For small creatures such as we the vastness is bearable only through love.

Do more

The longer I live, the more I realize the impact of attitude on life. Attitude, to me, is more important than facts. It is more important than the past, than education, than money, than circumstances, than failures, than successes, than what other people think or say or do. It is more important than appearance, giftedness or skill. It will make or break a company...a church....a home. The remarkable thing is we have a choice every day regarding the attitude we will embrace for that day. We cannot change our past...we cannot change the fact that people will act in a certain way. We cannot change the inevitable. The only thing we can do is play on the one string we have, and that is our attitude...I am convinced that life is 10% what happens to me and 90% how I react to it. And so it is with you...we are in charge of our attitudes.

Any sufficiently advanced technology is indistinguishable from magic.

Risk more than others think is safe. Care more than others think is wise. Dream more than others think is practical. Expect more than others think is possible.

A healthy man wants a thousand things, a sick man only wants one.

Privilege makes it possible to take ideological positions.

You will become way less concerned with what other people think of you when you realize how seldom they do.

Stay hard

I heard this story about a fish. He swims up to this older fish and says, "I'm trying to find this thing they call the ocean." "The ocean?" says the older fish. "That's what you're in right now." "This?" says the young fish. "This is water. What I want is the ocean."

To the world you may be one person; but to one person you may be the world.

Great minds discuss ideas; average minds discuss events; small minds discuss people.

Happiness is not a goal...it's a by-product of a life well lived.

All models are wrong, but some are useful.

What do I think? Who the fuck am I?

Any sufficiently advanced incompetence is indistinguishable from malice.

Never attribute to malice that which is adequately explained by incompetence.

Carpe diem

Of course it is happening inside your head, Harry, but why on earth should that mean that it is not real?

Not all those who wander are lost.

Every action you take is a vote for the type of person you wish to become.

We choose to go to the moon in this decade and do the other things, not because they are easy, but because they are hard, because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one which we intend to win.

For each desired change, make the change easy (warning: this may be hard), then make the easy change.

Are you not a soldier? Are you not a leader of men? Master yourself!

Death can have me when it earns me.

If you can’t get out of it, get into it.

New beginnings are often disguised as painful endings.

You must be the change you want to see in the world.

It's not the size of the dog in the fight, it's the size of the fight in the dog.

The secret of getting ahead is getting started.

The two most important days in your life are the day you are born, and the day you find out why.

Twenty years from now you will be more disappointed by the things you didn’t do than by the ones you did do. So throw off the bowlines. Sail away from the safe harbor. Catch the trade winds in your sails. Explore. Dream. Discover.

You used to think this was impossible. This moment, right here. Not too long ago, either.

I've learned that people will forget what you said, people will forget what you did, but people will never forget how you made them feel.

When most people say they want to be a millionaire, what they really mean is "I want to spend a million dollars," which is literally the opposite of being a millionaire.

People are often unreasonable, illogical and self centered; Forgive them anyway. If you are kind, people may accuse you of selfish, ulterior motives; Be kind anyway. If you are successful, you will win some false friends and some true enemies; Succeed anyway. If you are honest and frank, people may cheat you; Be honest and frank anyway. What you spend years building, someone could destroy overnight; Build anyway. If you find serenity and happiness, they may be jealous; Be happy anyway. The good you do today, people will often forget tomorrow; Do good anyway. Give the world the best you have, and it may never be enough; Give the world the best you've got anyway. You see, in the final analysis, it is between you and your God; It was never between you and them anyway.

Life begins at the end of your comfort zone.

Tell your heart that the fear of suffering is worse than the suffering itself.

One day or day one, you decide.

Reality is that which, when you stop believing in it, doesn't go away.

A wise man once said nothing at all.

To laugh often and much; to win the respect of the intelligent people and the affection of children; to earn the appreciation of honest critics and endure the betrayal of false friends; to appreciate beauty; to find the beauty in others; to leave the world a bit better whether by a healthy child, a garden patch, or a redeemed social condition; to know that one life has breathed easier because you lived here. This is to have succeeded.

The best-laid plans of mice and men often go awry.

Two roads diverged in a wood, and I - I took the one less traveled by, and that has made all the difference.

Perhaps the most valuable result of all education is the ability to make yourself do the thing you have to do, when it ought to be done, whether you like it or not; it is the first lesson that ought to be learned; and, however early a man's training begins, it is probably the last lesson that he learns thoroughly.

Honesty is the first chapter in the book of wisdom.

Don't inflict help

... but that doesn't mean you shouldn't build things anyway. Just because something is going to break in the end doesn't mean that it can't have an effect that lasts into the future. Joy. Wonder. Laughter. Hope. The world can be better because of what you built in the past... try and make sure that the things you're working on pushes in the right direction. They don't have to be big projects. They might just have an audience of one. And even if they don't last, try to make sure that they leave something positive behind.

Marriage is hard. Divorce is hard. Choose your hard. Obesity is hard. Being fit is hard. Choose your hard. Being in debt is hard. Being financially disciplined is hard. Choose your hard. Communication is hard. Not communicating is hard. Choose your hard. Life will never be easy. It will always be hard. But we can choose our hard. Pick wisely.

Nothing is stronger than an idea whose time has come.

With great power comes great responsibility.

The most carefree time of your life is over. That's a fact. You're an adult now, and unless your parents are filthy rich, you can never go back to thinking about the world the way a child does, where all of your needs are someone else's responsibility and you simply focus on what you want. But that was always going to end. And what's more, the older you get, the more you'll find that it wouldn't even make you happy to have it back. Because pleasure is not happiness, except when you're a child. Where you once sought pleasure, now you are old enough and smart enough to seek fulfillment. This is the time of your life when you get to really know yourself, find out what's meaningful to you, what you care about enough to go after it with all of your ability. And then you have the rest of your life to do those things! That's where your happiness will be found. There and nowhere else.
