So all of this stuff means that luck doesn't exists at all?!
... I do think luck exists. Some people just get lucky and have amazingly great health in face of everything else (e.g., smokers who live to be 90 years old). Or some get amazing breaks in their jobs, such as some musicians being discovered vs. other ones who put the same amount of time and energy in practice and networking and still get nowhere. I wonder how you'd create that kind of luck, though?
