Measuring programming progress by lines of code is like

“Every person in your company is a vector. Your progress is determined by the sum of all vectors.  ” ― Elon Musk

“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

“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

“A brand for a company is like a reputation for a person. You earn reputation by trying to do hard things well.” ― Jeff Bezos

“Most big technology companies are competitor focused. They see what others are doing, and then work to fast follow. In contrast, 90 to 95 percent of what we build in AWS is driven by what customers tell us they want.” ― 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

“In terms of the Internet, it's like humanity acquiring a collective nervous system. Whereas previously we were more like a [?], like a collection of cells that communicated by diffusion. With the advent of the Internet, it was suddenly like we got a nervous system. It's a hugely impactful thing.” ― Elon Musk

“The only rules are the ones dictated by the laws of physics. Everything else is a recommendation” ― Elon Musk

“Investors should be skeptical of history-based models. Constructed by a nerdy-sounding priesthood using esoteric terms such as beta, gamma, sigma and the like, these models tend to look impressive. Too often, though, investors forget to examine the assumptions behind the models. Beware of geeks bearing formulas. ” ― Warren Buffett

I think a simple rule of business is, if you do the things that are easier first, then you can actually make a lot of progress. ― Mark Zuckerberg

“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

“Solar cells, for example, got almost 10 times cheaper between 2010 and 2020, and the price of a full solar system went down by 11 percent in 2019 alone.” ― Bill Gates

“Invention is by its very nature disruptive. If you want to be understood at all times, then don't do anything new.” ― 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

“I insist on a lot of time being spent, almost every day, to just sit and think. That is very uncommon in American business. I read and think. So I do more reading and thinking, and make less impulse decisions than most people in business. I do it because I like this kind of life.” ― Warren Buffett

“I made so many mistakes in running the company so far, basically any mistake you can think of I probably made. I think, if anything, the Facebook story is a great example of how if you're building a product that people love you can make a lot of mistakes” ― Mark Zuckerberg

“Getting the team to a good state is not a milestone by itself that I care about.” ― 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

Facebook is inherently viral. There are lots of sites that include a contact importer, and for lots of them it doesn't really make sense. For Facebook it fits so well. It wasn't until a few years in that we started building some tools that made it easier to import friends to the site. That was a huge thing that spiked growth. ― Mark Zuckerberg

You can use your real identity, or you can use phone numbers for something like WhatsApp, and pseudonyms for something like Instagram. But in any of those you're not just sharing and consuming content, you are also building relationships with people and building an understanding of people. ― Mark Zuckerberg
