Reading zhao's story inspired me so much. the success he got did not come from wealth, he got it starting from 0. This proves that anyone can be successful as long as they are willing to walk through the process. I hope we can be successful like him.
Never underestimate right networking and luck, its obvious that he worked really hard but he is far from being the first person to work hard in the world, richness doesn't equal working hard, richest people are not the hardest workers, there are miners down hundred feets under ground mining copper or coal every single day for hours and I can clearly say they work harder than Elon, bill gates, warren buffet, jeff bezos and CZ all combined.
The difference is if you are a smart person like CZ and get lucky and also have the right networking that would end up with you getting richer, and not even at that point because sometimes it fails even though you did everything you should do right sometimes you get unlucky.
