What is my measure of success in life?
Is it longevity – as in number of years;
is it progeny – as in number of children, grandchildren, great grandchildren;
is it legacy – as in an invention or idea that lives on well, or forever, after my physical death;
is it making a difference – immediate, nominal, or see above;
is it helping others – immediate, nominal, or permanent?
Else – is measure of success in life a red herring;
as in – you will never die, you were never born, live in this moment of now?
