There are many people who proved to be real workaholics on their way to success. One of them is Nissan and Renault CEO Carlos Ghosn. He works more than 65 hours a week and his turnaround of Nissan arouses the interest of many business analysts. Facebook COO Sheryl Sandberg is another example of an industrious personality, she starts work at 7 AM and continues to get things done even after her kids are in bed.
There are many super-productive and hard-working people among sportsmen. Michael Jordan is known to take hundreds of jump shots every day during his offseasons.
