There absolutely is a takeaway - and it isn’t just that luck is important in winning - it’s that luck is
everything.
We like to live under the illusion that we are in control of our lives. We are not. We can set a general course, control this or that small, immediate thing - but so much of what we ascribe to our own success or failure is just sheer dumb luck.
I’ve had some ridiculous, absolutely undeserved successes over the years, I’ve been struck with serious illness out of the blue, I’ve seen friends with so many plans for their lives ahead snuffed out by illness and accident. I’ve seen the class clown rise to high office, and the prodigy work in a chip shop. We make choices, but against a sea of endless variables and influences, they make little difference.
People used to cite the fates, or their god or gods of choice - because they couldn’t explain the absolute randomness of the path of a life. I think you’ll find precious few people who, in their dotage, will say their life went to plan - and that doesn’t mean everyone’s a sad failure, rather that you end up places you never even dreamt of - because we really aren’t in control.
