You should never test the depth of the water with both feet.

“Second, most decisions should probably be made with somewhere around 70 percent of the information you wish you had. If you wait for 90 percent, in most cases, you’re probably being slow. Plus, either way, you need to be good at quickly recognizing and correcting bad decisions. If you’re good at course correcting, being wrong may be less costly than you think, whereas being slow is going to be expensive for sure.” ― Jeff Bezos

“The climate is like a bathtub that’s slowly filling up with water. Even if we slow the flow of water to a trickle, the tub will eventually fill up and water will come spilling out onto the floor. That’s the disaster we have to prevent. Setting a goal to only reduce our emissions—but not eliminate them—won’t do it.” ― 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

“You know the business plan won’t survive its first encounters with reality,” he says. “But the discipline of writing the plan forces you to think through some of the issues and to get sort of mentally comfortable in the space. Then you start to understand, if you push on this knob, this will move over here and so on. So, that’s the first step.” ― Jeff Bezos

“Until July, Amazon.com had been primarily built on two pillars of customer experience: selection and convenience. In July, as I already discussed, we added a third customer experience pillar: relentlessly lowering prices. You should know that our commitment to the first two pillars remains as strong as ever.” ― 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 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

“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

“I like it when people say, ‘Gee, that’s a pretty good-looking painting.’ But it’s my painting, and when somebody says, ‘Why don’t you use more red instead of blue?’ Good-bye. It’s my painting. And I don’t care what they sell it for. The painting itself will never be finished. That’s one of the great things about it.” ― 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

The amount of trust and bandwidth that you build up working with someone for five, seven, 10 years? It's just awesome. I care about openness and connectedness in a global sense. ― 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

Back, you know, a few generations ago, people didn't have a way to share information and express their opinions efficiently to a lot of people. But now they do. Right now, with social networks and other tools on the Internet, all of these 500 million people have a way to say what they're thinking and have their voice be heard. ― Mark Zuckerberg

“I agree with people like Richard Dawkins that mankind felt the need for creation myths. Before we really began to understand disease and the weather and things like that, we sought false explanations for them. Now science has filled in some of the realm – not all – that religion used to fill.” ― Bill Gates

“Well, Steve [Jobs]… I think it’s more like we both had this rich neighbour named Xerox and I broke into his house to steal the TV set and found out that you had already stolen it.” ― 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

“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

“I studied every thing but never topped.. But today the toppers of the best universities are my employees" ― Bill Gates

“If you want to understand the kind of damage that climate change will inflict, look at COVID-19 and then imagine spreading the pain out over a much longer period of time.” ― Bill Gates

“The world uses more than 4 billion gallons every day. When you’re using any product at that kind of volume, you can’t simply stop overnight.” ― Bill Gates
