It's like somebody winning the lottery once, constantly investing all of their money into more lottery tickets, and going "holy shit, look at how smart I am at picking lottery numbers; I've already won something four times!"
Given that the lottery has a typical expected value of -$1.00 per ticket you really should revise your opinion of how lucky/smart these people who repeatedly make tens of billions by pouring all their money into tickets are.
Interesting that you would use as an example two people who ingeniously built complex systems, through lots of hard and clever work, to turn the odds in their favour.
What else can you do with your life after you're rich? Life is meaningless. Most of us strive for money - when you have money, what's left? You're the dog that caught the car.
