Does mark zuckerberg believe in the thought that the endpoint is when you sell the company or go public

Mark Zuckerberg does not believe in the thought that the endpoint is when you sell the company or go public; on the contrary, Mark Zuckberg stated in an interview with 60 Minutes that that's what other companies think. Mark Zuckerberg is more of a free thinker and strategist who makes his company decisions based on his own accord and the counsel from his top advisers. Yahoo once wanted to buyout Facebook, but Mark turned it down and still continues to succeed with Facebook to this day as the CEO. In my opinion, had Zuckerberg sold Facebook it would not have been his endpoint.
