you don't need work ethic to make it big, and you don't even need intelligence really. Sure in some situations intelligence is needed but you don't have to be a Gauss to make it big, its mostly luck. Hard work is rarely needed, this whole idea that if someone works hard they'll make it big or at the very least jump up a notch or two in the socioeconomic ladder is so false. There are plenty of people who work 100x as hard as Bill Gates or whatever other million/Billion-aire ever will in their life and will not ever see even 1% of the success that those people do, and it even harder for anyone that isn't a white male. Look, Bill has never had to worry about anything financial, which is a huge burden of relief. Imagine never having to worry about money, and if you felt like crap, could go out and emotionally buy stuff if you wanted to. His potential to do all that "hard work" was a lot easier than most because he was born into wealth, which gave him the chance, if he so wanted to, to put all his focus on one thing.
