Plato, who said, “the unexamined life is not worth living”, apparently never read Solomon et al who wrote, “everything is meaningless” . . . after examining HIS life.
It isn’t known when Solomon wrote this before or after getting married. But you’d think after the 700th marriage he’d have added an appendix to his ‘Meaningless Philosophy.’ And as far as history is known, no appendix or amendment has been discovered.
Examine your life, but not TOO closely. And in the meantime…get a hobby.
