Don't discount yourself, no matter what you're doing.

“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

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

“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

“our experience with newly-minted MBAs has not been that great. Their academic records always look terrific and the candidates always know just what to say; but too often they are short on personal commitment to the company and general business savvy. It’s difficult to teach a new dog old tricks.” ― Warren Buffett

I spend a lot of time just, you know, with my girlfriend and my dog. And I mean, we don't have a lot of furniture in our house, so it's really simple. And we're trying to build products for everyone in the world, right. And you don't want to get isolated to do that. ― Mark Zuckerberg

I think what we've found is that when you can use products with your friends and your family and the people you care about, they tend to be more engaging. I think that we're really going to see this huge shift where a lot of industry is and products are just going to be remade to be social. ― Mark Zuckerberg

“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

“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

“If everything you do needs to work on a three-year time horizon, then you’re competing against a lot of people. But if you’re willing to invest on a seven-year time horizon, you’re now competing against a fraction of those people… Just by lengthening the time horizon, you can engage in endeavors that you could never otherwise pursue” ― Jeff Bezos

“As a company grows, everything needs to scale, including the size of your failed experiments. If the size of your failures isn’t growing, you’re not going to be inventing at a size that can actually move the needle.” ― 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

“Excessive use of made up acronyms is a significant impediment to communication […] No one can actually remember all these acronyms and people don’t want to seem dumb in a meeting, so they just sit there in ignorance. This is particularly tough on new employees.” ― 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

“If you see somebody with even reasonable intelligence and a terrific passion for what they do and who can get people around them to march, even when those people can't see over the top of the next hill, things are gonna happen” ― Warren Buffett

When people are connected, we can just do some great things. They have the opportunity to get access to jobs, education, health, communications. We have the opportunity to bring the people we care about closer to us. It really makes a big difference. ― Mark Zuckerberg

Our mission is to connect every person in the world. You don't do that by having a service people pay for. ― Mark Zuckerberg

“In terms of doing things I take a fairly scientific approach to why things happen and how they happen. I don't know if there's a god or not...” ― Bill Gates

“So it's an absolute lie that has killed thousands of kids. Because the mothers who heard that lie, many of them didn't have their kids take either pertussis or measles vaccine, and their children are dead today. And so the people who go and engage in those anti-vaccine efforts -- you know, they, they kill children. It's a very sad thing, because these vaccines are important.” ― Bill Gates

“times with follow-up questions. Eventually it sank in. The world needs to provide more energy so the poorest can thrive, but we need to provide that energy without releasing any more greenhouse gases. Now the problem seemed even harder. It wasn’t enough to deliver cheap, reliable energy for the poor. It also had to be clean.” ― Bill Gates

“[Bill] Gates said he connected with [Eddy] Izzard even though it would appear they have nothing in common — but that might be the point the author is trying to communicate. "I've recently discovered that I have a lot in common with a funny, dyslexic, transgender actor, comedian, escape artist, unicyclist, ultra-marathoner, and pilot from Great Britain. Except all of the above," Gates wrote. "We're all cut from the same cloth. In his words, 'We are all totally different, but we are all exactly the same” ― Bill Gates
