PayPal cofounder, SpaceX founder, and Tesla CEO Elon Musk is known for his tireless work ethic, and in an interview with Vator, he advises other entrepreneurs to work twice as hard as everyone else to achieve success.
"You just have to put in 80- to 100-hour weeks every week," he tells Vator. "If other people are putting in 40-hour work weeks and you're putting in 100-hour work weeks, then, even if you're doing the same thing, you know that you will achieve in four months what it takes them a year to achieve."
This ability to keep pushing was on display in August 2008 after SpaceX's third unsuccessful attempt to launch a rocket into space. Musk put out a statement telling the world, "For my part, I will never give up and I mean never."
Seven weeks later, SpaceX became the first private company to successfully launch a rocket that reached orbit.
