Constantly think about how you could be doing things better.

“I think that's the single best piece of advice: constantly think about how you could be doing things better and questioning yourself.” ― Elon Musk

“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

“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

“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 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

“Somebody once said that in looking for people to hire, you look for three qualities: integrity, intelligence, and energy. And if you don’t have the first, the other two will kill you. You think about it; it’s true. If you hire somebody without [integrity], you really want them to be dumb and lazy.” ― Warren Buffett

“It takes 20 years to build a reputation and five minuted to ruin it. If you think about that you'll do things differently.” ― 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

“If you just work on stuff that you like and you’re passionate about, you don’t have to have a master plan with how things will play out.” ― 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

“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

“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

“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

“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

“I'm not trying to be anyone's savior. I'm just trying to think about the future and not be sad.” ― Elon Musk

“Stop being patient and start asking yourself, how do I accomplish my 10-year plan in 6 months? You will probably fail but you will be a lot further ahead of the person who simply accepted it was going to take 10 years.” ― Elon Musk

“Life needs to be more than just solving problems every day. You need to wake up and be excited about the future.” ― Elon Musk

“There have to be reasons that you get up in the morning and you want to live. Why do you want to live? What's the point? What inspires you? What do you love about the future?” ― Elon Musk

“If you're not concerned about AI safety, you should be. Vastly more risk than North Korea.” ― Elon Musk
