Probably...each one of us is born with the same amount ...the only difference being..it gets distributed unevenly across our life span.
Some people have their best(lucky) days in childhood.. and eventually run out of good fortune by the time they enter the job market.
Others struggle early on.. and strike it rich later in life.
For example...famous people have their highs are almost perfectly matched by their lows.
It almost like...GOD is trying to smooth out(even out) things.
There are people who have never had a truly great year....nor a truly horrible one. They are the average ones.
Obviously..as usual..there is no science to support this theory of luck distribution...
