Mark Zuckerberg

Mentor: Steve Jobs, Sean Parker and Don Graham

Don Graham met Zuckerberg through his daughter who was studying in Harvard. The duo mentored each other, as the CEO of Washington Post needed help with social media while the CEO of facebook got his lessons on how to run a company.

Zuckerberg always had advices from Steve Jobs and the former always repeats the latter’s advice “Focus on building as high quality and good things as you are." When Steve Jobs passed away, Zuckerberg posted on his facebook wall "Steve, thank you for being a mentor and a friend. Thanks for showing that what you build can change the world. I will miss you."
