John F. Kennedy's

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 we intend to win, and the others, too.

Donald Knuth, in "Computer Programming as an Art" (1974),

The real problem is that programmers have spent far too much time worrying about efficiency in the wrong places and at the wrong times; premature optimization is the root of all evil (or at least most of it) in programming.

Yoda in "The Empire Strikes Back":

You must unlearn what you have learned.

William Gibson:

The future is already here — it's just not very evenly distributed.

If we wish to count lines of code, we should not regard them as lines produced, but as lines spend.

– Edsger Dijkstra

投资,在早期,更多的是艺术,不是科学,不是数据。八年以前,有多少人中午晚上吃外卖 的,多少人现在会去吃外卖,现在很多餐厅自己都在做外卖。什么叫艺术呢?就是你对这个 行业的想象力。你说这个团购行业有多大,咱们能不能量化一下,是两百亿呢还是两千亿呢, 还是两万亿?我感觉在当时你还真的很难去把它量化。

数学课上经常看英语书,然后看科幻世界,数学老师把我的书都撕掉了,然后扔到我脸上, 然后说你给我滚出去,你是全世界最差的学生。我后来想了想那个老师其实也挺无奈的,他 也很想帮助每个孩子,但是他没有这样的精力,和所谓的这样一个工具。

女性会给自己铁标签,就像胖子会觉得自己很胖,没信心,我从小就很胖,所以我是个胖子; 我原来这个高中没读完对吧,辍学这也是个标签。其实我觉得更多的是,我们自己不要给自 己贴标签,不要给自己设一个局限。可能创业这个事情,的确是有很大的冒险,运气成分在, 真正去做且做成的人,可能他们都需要一些共同的特质,这个特质其实不一定是男女的区别。

我未来的梦想是可以去帮助成千上万的小朋友,更好的学习和成长,然后这个事情没有头。 我们团队里面经常自己讲说,今天做到了几分,如果满分是一百分的话,我们觉得只做到了 一分。

戴琨 in an interview:

德州扑克里面其实最关键的问题就是,你其实真真正正你可能打二十把,能赢钱的就那两把。 就15分钟。这15分钟你是不是把注打够了。当你只有一点点的chips的时候,你如果不下注, 你光打底就死了。那在这个时候呢,我觉得是搏大的。就是需要在有胜算的时候all in进去。 我们在第6个月的时候,账面上就剩两三百万美元了。但是到那个位置了你不可能停下来嘛。 你补了5个月,你停下来,你不就证明自己错了吗。于情于理死撑也得撑着。晚上睡不着觉 我就不睡,我就起来跑步,我去跑一个小时,跑到筋疲力尽,我可以把自己累晕过去,但是 我在这种状态下我会保证一个好的睡眠。

Jeff Bezos in an interview video on Regret Minimization Framework:

(My boss says) (selling book online) sounds like really a good idea to me. But it sounds like a BETTER idea for somebody who DIDN'T ALREADY HAVE A GOOD JOB. Hahahahahhahahahhahahah

I wanted to project myself forward to age 80 and say okay now I'm looking back on my life I want to have minimized the number of regrets I have. And I knew that when I was 80, I was not going to regret having tried this. I was now going to regret having tring to participate in this thing called the internet that I thought was going to be a really big deal. And I knew that if I failed, I wouldn't regret that. But I knew one thing I might regret is not ever having tried and I knew that that would haunt me every day. So when I thought about it that way, it was an incredibly easy decision, and I think that's very good if you can project yourself out to the age 80, and think what will I think at that time, it gets you away from some of the daily pieces of confusion.

  • do I want to spend a lot of time around them?

10.2 Steve Jobs

2010 interview:

What I love about the consumer market, that I always hated about the enterprise market, is that we come up with a product, we try to tell everybody about it, and every person votes for themselves. They go 'yes' or 'no,' and if enough of them say 'yes,' we get to come to work tomorrow. That's how it works. It's really simple. With the enterprise market, it's not so simple. The people that use the products don't decide for themselves, and the people that make those decisions sometimes are confused. We love just trying to make the best products in the world for people and having them tell us by how they vote with their wallets whether we're on track or not.

Just because we're competing with someone doesn't mean we have to be rude.

From Steve Jobs’ Commencement address on June 12, 2005:

My third story is about death.

When I was 17, I read a quote that went something like: “If you live each day as if it was your last, someday you’ll most certainly be right.” It made an impression on me, and since then, for the past 33 years, I have looked in the mirror every morning and asked myself: “If today were the last day of my life, would I want to do what I am about to do today?” And whenever the answer has been “No” for too many days in a row, I know I need to change something.

Remembering that I’ll be dead soon is the most important tool I’ve ever encountered to help me make the big choices in life. Because almost everything — all external expectations, all pride, all fear of embarrassment or failure — these things just fall away in the face of death, leaving only what is truly important. Remembering that you are going to die is the best way I know to avoid the trap of thinking you have something to lose. You are already naked. There is no reason not to follow your heart.

About a year ago I was diagnosed with cancer. I had a scan at 7:30 in the morning, and it clearly showed a tumor on my pancreas. I didn’t even know what a pancreas was. The doctors told me this was almost certainly a type of cancer that is incurable, and that I should expect to live no longer than three to six months. My doctor advised me to go home and get my affairs in order, which is doctor’s code for prepare to die. It means to try to tell your kids everything you thought you’d have the next 10 years to tell them in just a few months. It means to make sure everything is buttoned up so that it will be as easy as possible for your family. It means to say your goodbyes.

I lived with that diagnosis all day. Later that evening I had a biopsy, where they stuck an endoscope down my throat, through my stomach and into my intestines, put a needle into my pancreas and got a few cells from the tumor. I was sedated, but my wife, who was there, told me that when they viewed the cells under a microscope the doctors started crying because it turned out to be a very rare form of pancreatic cancer that is curable with surgery. I had the surgery and I’m fine now.

This was the closest I’ve been to facing death, and I hope it’s the closest I get for a few more decades. Having lived through it, I can now say this to you with a bit more certainty than when death was a useful but purely intellectual concept:

No one wants to die. Even people who want to go to heaven don’t want to die to get there. And yet death is the destination we all share. No one has ever escaped it. And that is as it should be, because Death is very likely the single best invention of Life. It is Life’s change agent. It clears out the old to make way for the new. Right now the new is you, but someday not too long from now, you will gradually become the old and be cleared away. Sorry to be so dramatic, but it is quite true.

Your time is limited, so don’t waste it living someone else’s life. Don’t be trapped by dogma — which is living with the results of other people’s thinking. Don’t let the noise of others’ opinions drown out your own inner voice. And most important, have the courage to follow your heart and intuition. They somehow already know what you truly want to become. Everything else is secondary.

Here’s to the crazy ones, the misfits, the rebels, the troublemakers, the round pegs in the square holes… The ones who see things differently — they’re not fond of rules… You can quote them, disagree with them, glorify or vilify them, but the only thing you can’t do is ignore them because they change things… They push the human race forward, and while some may see them as the crazy ones, we see genius, because the ones who are crazy enough to think that they can change the world, are the ones who do.

It’s better to be a pirate than to join the navy.

Stay hungry. Stay foolish.

Your work is going to fill a large part of your life, and the only way to be truly satisfied is to do what you believe is great work. And the only way to do great work is to love what you do. If you haven’t found it yet, keep looking. Don’t settle. As with all matters of the heart, you’ll know when you find it.

If you want to live your life in a creative way, as an artist, you have to not look back too much. You have to be willing to take whatever you’ve done and whoever you were and throw them away.

10.3 Alan Kay

People who are really serious about software should make their own hardware.

If you want to make money, don't start a startup; start an industry. That way you make trillions instead of billions.

Don't do incremental things; do evolution ones.

I had the fortune or misfortune to learn how to read fluently starting at the age of three. So I had read maybe 150 books by the time I hit 1st grade. And I already knew that the teachers were lying to me.

If you don't fail at least 90 percent of the time, you're not aiming high enough.

10.4 Albert Einstein

Two things are infinite: the universe and human stupidity; and I'm not sure about the universe

There are only two ways to live your life. One is as though nothing is a miracle. The other is as though everything is a miracle.

10.5 Paul Graham

There are few sources of energy so powerful as a procrastinating college student.

Odds are you just think whatever you're told.

You need three things to create a successful startup: to start with good people, to make something customers actually want, and to spend as little money as possible.

It's important for nerds to realize, too, that school is not life. School is a strange, artificial thing, half sterile and half feral. It's all-encompassing, like life, but it isn't the real thing. It's only temporary, and if you look, you can see beyond it even while you're still in it.

It’s hard to do a really good job on anything you don’t think about in the shower.

But if you're trying to choose between two theories and one gives you an excuse for being lazy, the other one is probably right.

Don't ignore your dreams; don't work too much; say what you think; cultivate friendships; be happy.

You don't need people to give you advice that doesn't surprise you.

The difference between design and research seems to be a question of new versus good. Design doesn’t have to be new, but it has to be good. Research doesn’t have to be good, but it has to be new.

10.6 Peter Norvig

PowerPoint doesn't kill meetings. People kill meetings. But using PowerPoint is like having a loaded AK-47 on the table: You can do very bad things with it.

10.7 Pablo Picasso

Art is a lie that tells the truth

Good artists copy, great artists steal.

Learn the rules like a pro, so you can break them like an artist.

Computers are useless. They can only give you answers.

10.8 Wayne Gretzky

I skate to where the puck is going to be, not where it has been.

Only one thing is ever guaranteed, that is that you will definitely not achieve the goal if you don’t take the shot.

The day I stop giving is the day I stop receiving. The day I stop learning is the day I stop growing. You miss 100% of the shots you don’t take.

If you surround yourself with quality people and great friends, the sky’s the limit.

Not doing it is certainly the best way to not getting it.
