Diversification is protection against ignorance. It makes

“There comes a time when you ought to start doing what you want. Take a job that you love. You will jump out of bed in the morning. I think you are out of your mind if you keep taking jobs that you don't like because you think it will look good on your resume. Isn't that a little like saving up sex for your old age?” ― Warren Buffett

“When I was sixteen, I had just two things on my mind - girls and cars. I wasn't very good with girls. So I thought about cars. I thought about girls, too, but I had more luck with cars. Let's say that when I turned sixteen, a genie had appeared to me. And that genie said, 'Warren, I'm going to give you the car of your choice. It'll be here tomorrow morning with a big bow tied on it. Brand-new. And it's all yours.' Having heard all the genie stories, I would say, 'What's the catch?' And the genie would answer, 'There's only one catch. This is the last car you're ever going to ge tin your life. So it's got to last a lifetime.' If that had happened, I would have picked out that car. But, can you imagine, knowing it had to last a lifetime, what I would do with it? I would read the manual about five times. I would always keep it garaged. If there was the least little dent or scratch, I'd have it fixed right away because I wouldn't want it rusting. I would baby that car, because it would have to last a lifetime. That's exactly the position you are in concerning your mind and body. You only get one mind and one body. And it's got to last a lifetime. Now, it's very easy to let them ride for many years. But if you don't take care of that mind and that body, they'll be a wreck forty years later, just life the car would be. It's what you do right now, today, that determines how your mind and body will operate ten, twenty, and thirty years from now.” ― Warren Buffett

“When you receive criticism from well-meaning people, it pays to ask, ‘Are they right?’ And if they are, you need to adapt what they’re doing. If they’re not right, if you really have conviction that they’re not right, you need to have that long-term willingness to be misunderstood. It’s a key part of invention.” ― Jeff Bezos

“I think it’s important to reason from first principles rather than by analogy. The normal way we conduct our lives is we reason by analogy. [With analogy] we are doing this because it’s like something else that was done, or it is like what other people are doing. [With first principles] you boil things down to the most fundamental truths…and then reason up from there.” ― Elon Musk

Think about what people are doing on Facebook today. They're keeping up with their friends and family, but they're also building an image and identity for themselves, which in a sense is their brand. They're connecting with the audience that they want to connect to. It's almost a disadvantage if you're not on it now. ― Mark Zuckerberg

“If you're doing anything interesting in the world, you are going to have critics. You can't stop it. Move forward. It's not worth losing any sleep over.” ― Jeff Bezos

“When something is important enough, you do it even if the odds are not in your favour.” ― Elon Musk

“I mean, I think that if people are concerned about volatility, they should definitely not buy our stock. I’m not here [on an earnings call] to convince you to buy [Tesla] stock. Do not buy it if volatility is scary. There you go.” ― Elon Musk

“When something is is important enough, you do it anyway even if the odds are not in your favor.” ― Elon Musk

“So smile when you read a headline that says “Investors lose as market falls.” Edit it in your mind to “Disinvestors lose as market falls—but investors gain.” Though writers often forget this truism, there is a buyer for every seller and what hurts one necessarily helps the other. (As they say in golf matches: “Every putt makes someone happy.”)” ― Warren Buffett

“Gold is a way of going long on fear, and it has been a pretty good way of going long on fear from time to time. But you really have to hope people become more afraid in a year or two years than they are now. And if they become more afraid you make money, if they become less afraid you lose money, but the gold itself doesn’t produce anything.” ― Warren Buffett

“It is better to be hated for what you are than to be loved for what you are not.” ― Andre Gide

“Computers are great because when you're working with them you get immediate results that let you know if your program works. It's feedback you don't get from many other things.” ― Bill Gates

“There are two numbers you need to know about climate change. The first is 51 billion. The other is zero. Fifty-one billion is how many tons of greenhouse gases the world typically adds to the atmosphere every year.” ― Bill Gates

“Earlier, I mentioned a related technology called direct air capture. It involves exactly what the name implies: capturing carbon directly from the air. DAC is more flexible than point capture, because you can do it anywhere. And in all likelihood, it’ll be a crucial part of getting to zero; one study by the National Academy of Sciences found that we’ll need to be removing about 10 billion tons of carbon dioxide a year by mid-century and about 20 billion by the end of the century.” ― Bill Gates

“If you decide that you’re going to do only the things you know are going to work, you’re going to leave a lot of opportunity on the table.” ― Jeff Bezos

“Most people,” he said, “think that if they work hard, they should be able to master a handstand in about two weeks. The reality is that it takes about six months of daily practice. If you think you should be able to do it in two weeks, you’re just going to end up quitting.” ― Jeff Bezos

“I think it's very important to have a feedback loop, where you're constantly thinking about what you've done and how you could be doing it better.” ― Elon Musk

“If you do not like it then life is too short” ― Elon Musk

“It's nice to have a lot of money, but you know, you don't want to keep it around forever. I prefer buying things. Otherwise, it's a little like saving sex for your old age.” ― Warren Buffett
