Mark Cuban explains how to launch a company without raising a single dollar: Cuban argues that the vast majority of small businesses can get off the ground without any outside capital at all. "Most businesses, I'd say at least 90, if not 95% or more percentage of small businesses, startups can start without raising any capital at all. You just use sweat equity." His advice is to start lean: "You just have to try to start smarter, smaller." But Cuban is honest that the early stage isn't glamorous. The real challenge, he explains, comes down to a tension between paying your bills and building something of your own. "The hard part for most people is that tradeoff between do I keep my job or how do I start a company when I have a job? I worked as a bartender at night." @mcuban continues: "Whatever you have to do, that's part of being an entrepreneur. So if you have to work on weekends, you have to Uber at night, Uber on weekends so you have some income coming in so you can work on your... company, or you work your regular job during the week and at night and weekends, that's when you work on your startup." For Cuban, this is actually the good news, because it means the door is open to anyone willing to put in the hours: "Anybody can be an entrepreneur if they're willing to work their ass off 24 hours. That's what it takes." He sums it up with a line that captures the whole philosophy: "Entrepreneurs work 80 hours so they don't have to work 40."

Jeff Bezos on why stress is almost always a sign that you're avoiding action: When times are rough, Bezos doesn't talk about willpower or pushing through. He reframes where stress actually comes from. "I find if I'm stressed about something, it's usually because I'm not doing anything about it," he says. For Bezos, stress is information. He treats it as a physical signal worth paying attention to: "If I'm stressed about something, I'm trying to figure out why am I stressed? I'm listening to my body as a signal that something is awry." And the relief comes from simply starting to move on it: "The stress goes away the second I take the first step of identifying the source of the stress. Why am I stressed about this? What's going on?" The next step is to stop carrying it alone. Bezos talks to someone, and more specifically, he looks for allies: "If you can find friends who are interested in similar things or want to help you solve a problem, problem solving is inspiring for me all by itself." This is where the shift happens. Once @JeffBezos has people around him, the same situation that once felt heavy becomes something he enjoys: "There's nothing more fun than getting in a room with a group of inventors and saying, 'Look, here's the problem. Let's invent a solution to it.' And as soon as you start doing that, I find that it turns from something that might create stress into something that creates fun."
