Entrepreneur and author Timothy Ferriss believes that 4 hours a week is all anyone needs to accomplish pretty much anything. He has written books for work, fitness, and cooking that promote that idea of getting more done in less time. “The 4-Hour Workweek” has been his top bestseller.

He has featured in and received accolades from major publications and organizations, such as The New York Times, The Wall Street Journal, and Fortune magazine. Meanwhile, other entrepreneurs often come to him for his support as their angel investor. His investments have paid off in a number of successful apps.

After graduating from Princeton University, he moved from a job in technology sales to starting an online nutritional supplements company within a couple of years. He now also hosts a popular podcast that regularly features celebrities like LeBron James, Neil Gaiman, and Dr. Jane Goodall.
