There's never just one cockroach in the kitchen.

“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

“There’s one last way we can cut down on emissions from the food we eat: by wasting less of it. In Europe, industrialized parts of Asia, and sub-Saharan Africa, more than 20 percent of food is simply thrown away, allowed to rot, or otherwise wasted. In the United States, it’s 40 percent. That’s bad for people who don’t have enough to eat, bad for the economy, and bad for the climate. When wasted food rots, it produces enough methane to cause as much warming as 3.3 billion tons of carbon dioxide each year.” ― Bill Gates

“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

“No matter how great the talent or efforts, some things just take time. You can't produce a baby in one month by getting nine women pregnant.” ― Warren Buffett

“Technology is just a tool. In terms of getting the kids working together and motivating them, the teacher is the most important.” ― Bill Gates

“There’s no magic line between an application and an operating system that some bureaucrat in Washington should draw. It’s like saying that as of 1932, cars didn’t have radios in them, so they should never have radios in them.” ― 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

“I’ve been thinking a lot about the importance of good friendships in my life. I’ve come to the same conclusion as [one] Harvard study on human life: good relationships make you happier and healthier.” ― Bill Gates

“I wanted to project myself forward to age 80 and say, ‘OK, I’m looking back on my life. I want to minimise 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 not going to regret trying to participate in this thing called the Internet that I thought was going to be a really big deal. I knew that if I failed, I wouldn’t regret that. But I knew the one thing I might regret is not ever having tried. I knew that that would haunt me every day.” ― 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

“When I was a little kid, I was really scared of the dark. But then I came to understand, dark just means the absence of photons in the visible wavelength--400 to 700 nanometers. Then I thought, well, it's really silly to be afraid of a lack of photons. Then I wasn't afraid of the dark anymore after that.” ― Elon Musk

“I could go and buy one of the islands in the Bahamas and turn it into my personal fiefdom, but I am much more interested in trying to build and create a new company.” ― Elon Musk

“If humanity is to become multi-planetary, the fundamental breakthrough that needs to occur in rocketry is a rapidly and completely reusable rocket … achieving it would be on a par with what the Wright brothers did. It’s the fundamental thing that’s necessary for humanity to become a space-faring civilization. America would never have been colonized if ships weren’t reusable.” ― Elon Musk

“Science is discovering the essential truths about what exists in the Universe, engineering is about creating things that never existed” ― Elon Musk

“When I was a child, there's one thing I said: 'I never want to be alone.' That's what I would say.” ― Elon Musk

“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

“I wonder how many dead one-planet civilizations are out there in the cosmos that never made it to the other planet and ultimately extinguished themselves or were destroyed by external factors. Probably a few.” ― Elon Musk

“It's okay to have all your eggs in one basket as long as you control what happens to the basket.” ― Elon Musk

“If you’re trying to create a company, it’s like baking a cake. You have to have all the ingredients in the right proportion. There’s certain special skills, especially in advanced engineering, that are the limiting factor in creating new companies; we send these people home after training them in our graduate schools.” ― Elon Musk

“If you’re in the luckiest one per cent of humanity, you owe it to the rest of humanity to think about the other 99 per cent.” ― Warren Buffett
