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."
