Running a multinational company that plays a significant role in the lives of many people around the world is not easy. It takes great resilience to get ahead and stay on top.

Executives and CEOs from companies like Tesla, Apple and many more speak about their everyday routines to stay on top of their work. Some spend their birthdays working, others work more hours in a week than an average person does, and some do not take a vacation at all.

Let's take a look at the daily habits of these successful men and women:

1. Mark Cuban

Mark Cuban is a billionaire entrepreneur, investor, and a reality TV star. His holiday aversion is the result of his effort on "making it" as a businessman, he wrote in his blog. In the same post, he said that running a business is a 24/7 job where there is always someone out there to kick your ass.

2. Elon Musk

Many of us consider birthdays as an important part of our lives that even workaholics take a break to celebrate their birthday.

But it seems that it is not the case with Elon Musk, the CEO of Tesla. He said in a tweet that he will be spending his 48th birthday working on "global logistics." He described his 47th birthday in an interview on 2018 New York Times that it is an "all-night-no friends, nothing" 24-hour shift at his office.

3. Marissa Mayer

Talk about extreme, if Elon Musk works for 120 hours in a week Marissa Mayer took it 10 steps further. The ex-Yahoo CEO Marissa Mayer said in an interview in 2016 with Bloomberg that hard work is often overlooked by people who make stories about Google. Reporters tend to write about the company as if it was invincible, but the actual experience was more like saying yes to working for 130 hours per week which most people can't do.

4. Tim Cook

Apple CEO Tim Cook wakes up at 3:45 in the morning to exercise and check emails. He is one of the earliest birds among other tech executives in Silicon Valley who also wakes up early in the morning. Business Insider Dave Johnson copied Cook's routine and was surprised to find that it made him more productive.

Cook told TIME magazine that when you love what you do, you'll never think of it as work. Lucky for him, he found a job that he loves.

5. Jack Dorsey

Twitter and Square CEO Jack Dorsey eats only one meal of meat or fish with green vegetables during weekdays. He says that it helps him work more effectively.

The CEO of Oracle is known for his Midas touch because he hands out gold coins as bonuses to his employees in order to motivate them.
